A 企鹅 is a passive 小动物. It only spawns in the 雪原生物群落 and may spawn with different colors. The Penguin behaves as the other normal ground critters: it wanders around randomly as any other critter would, and it can easily be killed by other mobs. Penguins can be caught using the 虫网, at which point they can be carried around in the inventory and released again later. You can also sell them or craft them into a 企鹅笼 that can be used as animated furniture. Once crafted, the penguin cannot be released again.
The Penguin Cage occupies a 6x3 space. The Penguin inside may follow the following patterns randomly:
Penguins become 腐化企鹅s or 毒企鹅s during a 血月 and will try to attack the player just like the other enemies. They can also be turned into their Corruption/Crimson variants with 魔粉 or 毒粉. They cannot be caught with a Bug Net in this state.
