The 胡萝卜 summons an exclusive pet Bunny that is only available in the Terraria Collector's Edition. The color of the bunny's fur is defined by the shirt color chosen for the character at the point of their creation.
- It is only available to players who have purchased the Collector's Edition of Terraria — new characters created by them will spawn with it. While it can be traded, players who do not have the Collector's Edition will not be able to use it.
- To avoid network incompatibility, and to make updates easier, the data corresponding to the pet bunny is present in all PC versions; however only players identified as owning the CE will spawn with a 胡萝卜 and be able to use it. It is, however, missing entirely from the 主机版.
- The item is obtainable through inventory editors and maps but is unusable.
- The publisher of the Collector's Edition requested an exclusive in-game feature, so as to motivate people to purchase the more expensive physical copy instead of the digital download version of the game. To avoid unbalancing the game, Redigit chose to comply with a relatively inconsequential feature.
