Halloween // Group of 6 (2 toddlers)

Hoping at least a few people find this and have some suggestions! My best friend and I had our babies just a few months apart so we're wanting to do a big group Halloween this year. Looking for some ideas that will fit 4 adults (2 M & 2 F) and 2 toddlers (14 & 18 months, both girls, & assume both are walking).

We've been toying with a group Super Mario costume but my husband isn't completely sold. So just looking for some fun ideas!!
