Yoshi's Tropical Island

"This is where the Yoshis live..., Watermelon Island and Cantaloupe Island. The Yoshi on the middle island is surrounded by whirlpools, and can't get off the island! That Yoshi's best friend is worried, and watches from the shore. Please, do something! I have one piece of advice! Beware of Bubba! He plays tricks on the ? Space."

Yoshi's Tropical Island is Yoshi's board in Mario Party. It consists of Watermelon Island on the left, Cantaloupe Island on the right (both islands are shaped like two Yoshis), two adjoining bridges, and a small island in the middle. A shipwreck appears to the north of Watermelon Island, though it is not part of the actual board.

Many Yoshis are said to live here, though only two are shown on the board. A Pink Yoshi is on the small island and is surrounded by whirlpools, while a Blue Yoshi is watching from Watermelon Island, unable to do anything about it. Players need to collect Stars to get rid of the whirlpools and reunite the two Yoshis.

At the end of the game, the winner's Stars get rid of the whirlpools and form a bridge for the Blue Yoshi to cross to meet his friend on the small island. The winner quickly comes to the island as well, and the players in second and third place, Toad, Koopa, Boo, a Thwomp, and the Star follow. The player in fourth place tries to join them, but is captured and taken away by Bubba. Unlike other boards, the individual Stars do not merge into one big Star, and the whole board is not shown.

This board returns in Mario Party Superstars. In this game, the Yoshi on the central island is red, the island is surrounded by Cheep Cheeps instead of whirlpools, and Bubba is replaced by Cheep Chomp. Several Urchins can be seen floating in the water, and there is a Huckit Crab on the beach of Cantaloupe Island. There is now an Item Shop run by Yellow Toad on Watermelon Island, and a drawing of Yoshi's face can be seen in the sand in the lower-right section of the board. At the end of the game, the losing players are swallowed and taken away by Cheep Chomps while the winning player is awarded the title of Super Star.

Layout
The board is divided into two islands with two one-way toll bridges between each one, with no other branching paths. This ensures that a player must pass either Toad or Bowser every time they circle an island, and must remain on the same island if they cannot afford to pay the toll to cross.

Events

 * Stepping on the Happening Spaces will cause Bubba the fish (in Mario Party) or Cheep Chomp (in Mario Party Superstars) to take Toad/Toadette to the opposite island, and Bowser will come to the spot where Toad/Toadette was.
 * If a player passes Bowser, he will force them to buy a defective Bowser Tube for 30 Coins in Mario Party and a random number of coins in Mario Party Superstars. In Superstars, he may instead forcibly sell a Cursed Dice Block to the player who passes him for 11-20 coins; if that is the player in the last place, he may give them 5 coins.
 * Two Thwomps block the bridges to the opposite island, and request a fee from players if they want to pass to the other island. The fee always starts at 1 Coin, but goes up by at least one Coin each time (at payers' discretion) until it reaches the limit of 50 Coins (in Mario Party) or 999 Coins (in Mario Party Superstars) to pass. In Mario Party Superstars, it is possible to half the Thwomp's fee through a Lucky Space event.

Spaces
The following tables show how many spaces there are on the board, and how many there are of a certain type.

 * "Did you see the whirlpools? You can't cross over to the middle island."
 * "That Yoshi by the seashore is crying because he can't go see his friend."
 * "They're torn apart, those two Yoshis. They were the best of friends."
 * "As long as the whirlpools are there, that Yoshi can't see his friend. Oh, it's so sad!"
 * "If only some kind of strength could make that whirlpool go away!"
 * "Those poor, poor Yoshis. If only somehow, we could get them together."
 * "As a toll for passing, you must pay more than X Coins. Will you pass?" -Thwomp
 * "You're going to help the Yoshi in the middle, right? Here, take this. This is a mystical item, the Bowser Tube. You can use this! What happened? It broke? It must've been the wrong size. ...Have you gotten fatter? Well, that'll be 30 Coins!" -Bowser
 * "You're going to help the Yoshi in the middle, right? Here, take this. Oh! You don't have enough Coins! Oh well, I'll just take them all! See ya! Wah, hah, Hah, HAH!" -Bowser
 * "You're going to help the Yoshi in the middle, right? Here, take this. Oh! But you haven't got a single Coin! I'm outta here!" -Bowser
 * "Due to Bubba's trick, Toad and Bowser switched places."
