Door Hoverka Colosseum

The Door Hoverka Colosseum is a colosseum that hosts the Carta Colisseum (カルタコロシアム) competition. It is a parody of the Corrida Colosseum.

Carta Colisseum
Hosted by Carta, the Carta Colisseum consists of a card based on quickly identifying custom-made cards. Carta lays a deck of giant cards with unique images in rows on the ground, before reading a sentence that hints to one of them. Each player must then rush to the specified card, with the first person to reach it getting a point.

However, each card actually has a full body with the speed of a Super Spot-Billed Duck, developed by Carta based on Karoo's speed. The players must chase down the cards and fight through their defensive abilities, which are based on what the card represents.

At the end of the game, the person with the most points wins the game.

Chin Piece
Some time after Sabo ate the Mera Mera no Mi, Carta held the Carta Colisseum competition, promising the fruit as a prize. The prize attracted a large amount of competitors, including Chimpy, despite Kusopp's protests that the fruit was in Sabo's possession.

After the competition concluded, with Chimpy as its victor, Carta claimed that he made a spelling error on the prize announcement, and meant to reward "only a spatula" (へラへラのみ) instead of the "Mera Mera no Mi" (メラメラの).
