Captain Toad: Treasure Tracker (Nintendo Switch / Nintendo 3DS)

Captain Toad: Treasure Tracker is a puzzle-platformer for the Nintendo 3DS and Nintendo Switch, and a port of the Wii U game of the same name released in 2014. Unlike the original, they are prequels to Super Mario Odyssey instead of Super Mario 3D World.

Story
Captain Toad and Toadette are out treasure hunting, climbing a structure to get a Power Star. They soon after notice feathers falling from the sky when Wingo, a large bird who is described as "a lover of all things shiny", grabs the star. Toadette attempts to retrieve it while Captain Toad is temporarily knocked over. Wingo makes off with both the star and Toadette, leaving the Captain on his own. Captain Toad must then go through stages collecting Power Stars to reach Wingo and save Toadette.

Once Captain Toad reaches Wingo's fortress, they fight, and after Wingo is defeated, Toadette is rescued and they continue treasure hunting. However, Wingo returns to steal their treasure again and ends up capturing Captain Toad, allowing Toadette to journey on a solo adventure. After another long journey, Toadette saves him, although immediately afterward Wingo reappears, captures Toadette again and blows Captain Toad away.

The Captain awakes in a dark cave, where he finds another Power Star snatched away by Wingo. Toad pursues to a large mine. Meanwhile, Toadette escapes Wingo and goes off to reunite with Captain Toad, though is captured again soon after. Wingo then takes her to the same tower, while Captain Toad arrives. After a final fight, Wingo is truly defeated, and the two Toads ride off in a minecart as the credits play.

After the credits, the minecart goes to the Sand Kingdom and Captain Toad notices the Odyssey flying, and chases after it, leaving Toadette in the minecart.

amiibo
Like the Wii U version of the game, this game is compatible with amiibo. But, by scanning the Toad amiibo, instead of using it for hide and seek, it can be used for playing a level while invincible, similar to the effects when scanning a Mario amiibo in Super Mario Odyssey. In addition, the Wedding Mario, Peach, or Bowser amiibo unlocks the Super Mario Odyssey-themed courses early in the game. Any other amiibo can give Captain Toad 1-UP Mushrooms.

The Nintendo Switch version of the game can be played without the touch screen in TV mode and with the touch screen in handheld mode.

Two-player modes
In the Nintendo Switch version of the game, two types of cooperative two player modes are available in every level. Both of these modes are only available in the Nintendo Switch's TV / Tabletop mode.

Assist Mode
In Assist Mode, Player 1 assumes the normal role of Captain Toad or Toadette, except for the change that Player 2 now exclusively controls the pointer.

Player 2 also gains the ability to fire red turnips towards wherever the pointer is located. Red turnips can be used to obtain collectibles (except Super Gems and Power Stars), defeat enemies, or break small blocks. They cannot be used to activate switches, enter Clear Pipes, break Rock Blocks, or damage bosses. This mode also allows Player 2 to fire even during Mine Cart sections and to use the pointer when inside it, which is usually not possible.

This mode is only playable using two Joy-Con controllers. Joy-Con (L) is always assigned to Player 1, and Joy-Con (R) is assigned to Player 2. When switching the game to or from this mode, all controllers currently synced to the Switch will turn off. Attempting to sync another controller will fail. Syncing a controller in the Home Menu and then going back into the game will turn the newly synced controller off. Wired controllers will also appear desynced.

Adventure for Two
Adventure for Two was added in the 1.1.0 update on February 13, 2019. This mode allows both players to control a Toad Brigade Member, with Player 1 controlling the assigned character for the level, and in all episodes but Special Episode, Player 2 controlling a purple palette swap of Captain Toad. In Special Episode, Player 2 controls Toadette.

Any control method is available to both players in this mode, as well as a sideways Joy-Con. Notably, the button to rotate the camera in this mode was changed for the sideways Joy-con configuration, and a new button was added to activate the cursor. Additionally, both players can Bubble themselves to float above the other player's head, until they wish to pop out and continue playing.

When a player loses a life in this mode, they are sent into the Bubble. If a player is in a bubble or is in the process of losing a life as the other player does the same, the players must start the level over. If the players are too far apart from each other, one will automatically be warped to the other's location via bubble.

If either player is using a Spinwheel and the other approaches another Spinwheel, they cannot use it until the player actively using a Spinwheel steps off.

If either player enters a Clear Pipe cannon, or a Mine Cart, the other player will be warped there quickly. However, Doors, Pipes, Clear Pipes and others do not force the other player to warp.

Both players can collect Super Gems and Power Stars (or Power Moons / Shiny Crowns) in this mode. The player who reached the Power Star first is the one visible during the Course Clear animation.

Differences

 * In the Wii U version, the Bonus Episode features stages in locations from Super Mario 3D World. The Nintendo Switch and Nintendo 3DS versions replace these stages with ones based in kingdoms from Super Mario Odyssey.
 * To reflect this, the Episode 3 ending differs. In the Wii U version, the introduction cutscene of Super Mario 3D World plays after the credits, followed by a scene of Captain Toad entering a Clear Pipe to the Sprixie Kingdom. In the Switch and 3DS versions, the ending instead leads into Super Mario Odyssey, with Captain Toad running toward the Odyssey in the Sand Kingdom.
 * Unlike the Super Mario 3D World stages, the Super Mario Odyssey stages contain Super Gems.
 * The Toad amiibo is not needed to play "Hide & Seek," which is now accessible after beating a level.

Nintendo Switch only

 * The Nintendo Switch version features multiplayer, as well as the paid DLC Special Episode. These features are absent from both the Wii U and Nintendo 3DS versions.

Nintendo 3DS only

 * Due to hardware limitations, some of the bonus objectives in the Nintendo 3DS version of the game are changed, such as the one in Poison Canal Cannon Run being changed from "Cleared course with 4 Toadettes!" to "Found the hidden Gold Mushroom!".
 * Futhermore, the 3DS version uses the Super Mario 3D Land engine and runs at 30fps in comparison to the Wii U and Switch versions, using the Super Mario 3D World engine, running at 60fps.
 * Captain Toad's eyes in the Nintendo 3DS version are larger than in the Wii U or Nintendo Switch versions.

Stages
Captain Toad: Treasure Tracker features 79 stages (referred to as "mini-universes" ). The game is divided into various "episodes," with their own plots, as well as containing a number of different stages played as each character. Each stage also features a challenge that can be completed for an extra bonus.

An update for the Nintendo Switch version released on March 14, 2019, includes 18 new courses ranging from sunken ships to an area based on sweets.

Version 1.1.0 (Nintendo Switch)
The Nintendo Switch version of the game received an update on February 13, 2019, which added 2 Player co-op into the game. The update also added the Special Episode (if players pre-purchased the Captain Toad: Treasure Tracker - Special Episode content from the Nintendo eShop), allowing players to play the first level as a pre-purchase bonus.

This update also included changes to existing elements. Players can now toggle their character's headlamp by tapping the playable character with the pointer. Players may also toggle their partner's headlamp when playing in Adventure for Two mode. The second player in Assist Mode can toggle the first player's headlamp in this way.

A "Restart" button was added to the pause screen or every level. Restarting a level returns the player to their starting point or latest checkpoint, resets the timer and coin counter to 0, but retains all Super Gems they collected. Restarting does not cost lives. If the player restarts a level after a checkpoint, the timer will not be displayed and saved as their best time.

Additionally, this update made it no longer possible to run over Spinwheels in Handheld Mode, instead automatically snapping the player to them without touch screen input, same as in TV / Tabletop Mode.

Version 1.2.0 (Nintendo Switch)
The Nintendo Switch version of the game received an update on March 14, 2019, adding the remaining seventeen levels to the Special Episode for players that purchased the Captain Toad: Treasure Tracker - Special Episode content from the Nintendo eShop.

Additionally, to better distinguish the 2 players, Toadette's headlamp now has a distinctively warmer tone than that of Captain Toad's when playing in Adventure for Two mode in the Special Episode.
