That things like a Dragon Quest Sanguini; They look like cute, fuzzy little plushies but then show their mouths which is the size of their whole body along with crazy canines.
Excuse me, I need to go find/create a It's a Trap! pool.
The creature you see Samus holding here is not in fact a rabbit of any kind. It's the first of two stages that eventually metamorphose into the monstrous dragon that we know better as Ridley.
On the one hand, this is just too adorable for words. On the other hand, it's rather heartbreaking, considering Little Birdy will grow up to be one of Samus' deadliest enemies.
