Halloween // Penguin power!

Looking for inspiration! Picked up a penguin onesie from thrift store for $5 and my husband actually agreed to wear it for Halloween!!! (He’s not typically into anything and I’m not sure why I married him but besides the point lol...) Trying to find a theme or reference that would work with it for myself and 1.5 yr old kid.

Open to just other onesies for a group or making something. Not super into Mary Poppins...it’s the only thing coming to my mind besides Billy Madison but no one would get that reference I’m afraid. Any ideas!?!?
