A snake...cause I like snakes. I wish they did have pirate pets.
For the animations:
The Monkey
- Would run behind you while moving
- Would perch on your shoulder while standing still
- Would move from one perched shoulder to the other when using a weapon
The Snake
- Would just dangle from your neck
- Maybe when starting a fight it would slither around your neck
The Parrot
- Same as monkey but flying
