Boss idea:
Mush-Zilla: a huge dino which blasts fire and smashes and when he get hit two times he will starts blasting fire balls and smashing faster and also he can jump -high in the air and there will be an X in the air where he is going to land so you will be able to move in time
Weakness: when he smashes with his arms you can jump on them and wait for him to pull his arms up then you get the chance to jump on him.
Looks: either having a mushroom on its back (like a yoshi) or have spots on his head.
or if theres too much mushroom-ish you can use Mar-zilla as a name and his looks would be white arms red body and blue bottom. or you can pick what you want since your the one who is creating the game >_<
Other Ideas:
Crew heads: using the crew member's heads (Paul, Chris, etc etc)
