Each world will have a few mid-bosses. They will be slightly easier to defeat than the main bosses, but none the less crazy or fun.

Pirate Captain
In this battle, Snot must attack the pirate captain with snail shells while avoiding the cannonballs blasted by the Captain.
In actual fact, they are not cannonballs at all, but tiny round explosive pirates bombs!
There are three pirates aboard the pirate ship:
The Captain: the leader of the crew, he is not as fearless as he makes out
The Lookout: this guy sits atop the mast, his best friend is a parrot
The Drunk: likes to drink rum all day
Arrr! Blow the snail down!

More mid-bosses to come...
