The 7th puppet looks kind of weird - just a limb connected with the head, or stuff (the one farthest to the let ...) Not sure whether to treat it as a single puppet or not ... But why not.

Here some symbolism:
a) Regulars/ Biters, Runners, Jumpers, Smart Ones, Behemoths, Little Ones, Randy ...
b) 7 remaining Little Ones ... *dundunDUN*

Best wishes!
