Well the crabs were actually Calypso in her animal~like form. If you watch the movie when Jack is being brought to the sea in Davy Jone's Locker by the crabs, before he gets there, a bunch of crabs crawl up Tia Dalma/Calypso's dress, and she's also petting on and says: "Witty Jack is closer than you think."

Idk about the monkey though. :)
