Seesaw

Seesaws are a type of platform object that appear in many Super Mario games, and they usually tilt left or right depending on where the player and/or enemies walk on it.

Super Mario World 2: Yoshi's Island
Teeter-totters, also referred to as seesaws, first appear in Super Mario World 2: Yoshi's Island, where one is first found in the hidden ! Switch area in The Cave Of Chomp Rock. In this bonus area, a Yoshi must tilt the seesaw to collect the coins; if he falls off, he can no longer reach them and is forced to leave the area. A seesaw also appears in Burt The Bashful's Fort and in King Bowser's Castle.

Another, shorter variant, also called a teeter-totter, appearing as a bar of log similar to Spinning Logs, is found in later levels, first appearing in Watch Out For Lakitu. Each of these logs balances on a small point in the middle. Standing on them causes them to tilt and potentially fall unless a Yoshi is in the center. Most of the log-based ones are each situated on a post that ends in a wooden stake. The posts also sometimes have a different color like other posts, such as dark blue in cavern levels. Certain wobbling logs balance on other surfaces that are not dangerous to touch.

Yoshi's New Island
In Yoshi's New Island, both types of seesaws appear in the level Seesaw Scramble, with the larger variant also appearing in Gargantua Blargg Attacks!.

Yoshi's Woolly World / Poochy & Yoshi's Woolly World
In Yoshi's Woolly World and its port, seesaws appear in the levels Big Montgomery's Fort and Lava Scarves and Red-Hot Blarggs. They behave the same as in the New Super Mario Bros. games.

Super Mario 64 / Super Mario 64 DS
In Super Mario 64 and its remake, a seesaw that resembles a wooden bridge is located near the Chain Chomp on the Bob-omb Battlefield. Two seesaws appear in the final section of Bowser in the Dark World, two in The Secret Under the Moat, and one in Bowser in the Sky. Two seesaws made of stone appear in Rainbow Ride.

A turning platform similar to a seesaw appears in the initial section of Bowser in the Sky, and one is in the room that contains a bookcase in Big Boo's Haunt that drops the player into the merry-go-round area if they stand on it for too long.

Super Mario Advance 4: Super Mario Bros. 3
In Super Mario Advance 4: Super Mario Bros. 3, two seesaws appear in the World-e level A Towering Tour. Players can make them tilt left or right by placing themselves on the corresponding side, and the Seesaws can do a full 360° rotation.

New Super Mario Bros.
In New Super Mario Bros., two seesaws appear in World 1-2. One of them allows the player to access a gap at the top of the level, where the third Star Coin and the secret exit are located. They behave the same as the larger variant in Super Mario World 2: Yoshi's Island.

New Super Mario Bros. 2
Seesaws return in New Super Mario Bros. 2, only appearing in World 2-2 and World 6-5. They behave as they did in New Super Mario Bros.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
While Seesaws themselves do not appear in New Super Mario Bros. U, New Super Luigi U, or their remake, a similar type of seesaw, the Seesaw Shroom, appears in the former game as a type of Mushroom Platform, along with a blue variant in the latter game.

Super Mario Maker 2
Seesaws appear as a course element in Super Mario Maker 2. They are colored orange in the Super Mario World style, and red in all other styles. In the Super Mario Bros., Super Mario Bros. 3, and Super Mario World styles, they appear to be metallic, but in the New Super Mario Bros. U style, they are wooden. Like normal Lifts, their length can be changed, and they can be placed on tracks. They work similarly to their appearance in Super Mario Advance 4: Super Mario Bros. 3 (with the Super Mario Bros. 3-styled ones even resembling them), in that they tilt left or right depending on the player's or an enemy's position, but they can no longer do a full 360° rotation.

Seesaws can be abruptly tilted when a Thwomp falls on one side, throwing any playable characters and objects on the other side high into the air. This can also be achieved if a player Ground Pounds on the Seesaw (requiring a Dry Bones Shell to do so in the Super Mario World style and either a Dry Bones Shell or a big Goomba's Shoe in the Super Mario Bros. and Super Mario Bros. 3 styles). Furthermore, Bowser can perform this as well in the Super Mario Bros. 3 style using his Ground Pound attack.

Weight tier list
The following is a table listing the different weights of each course element.

In addition to these weight values:
 * Variations of a course element almost always weigh the same as their parent. This includes different forms of the player character.
 * Applying the Super Mushroom modifier to a course element doubles its weight. Wings and parachutes, on the other hand, contribute nothing to the weight.
 * While Giant Eggs have an initial weight value of 2×, the value becomes 1× once Red Yoshi hatches from the egg.
 * Pokeys and Snow Pokeys in particular have their weight multipliers increase by one for each segment added.

Unused appearances
While Seesaws do not appear in New Super Mario Bros. Wii, they appear without custom textures in the game's code, implying that they were originally meant to appear within the game.
