Halloween // Need ideas for mom, dad, and toddler—looking for funny or cute group costume

We have a two year old and would like to do a group costume this year. When she was a baby, we made her a lobster in a pot and we were chefs. Last year we were all penguins.

This year I’d like to avoid spending a lot of money on brand new costumes for all of us, but I’d also like to do something new and not just be penguins again.

I’d be okay with buying the toddler costume if we could do something DIY for the adults.

Any ideas for cute or funny costumes?
