I hadn't made a proper reference for these little creatures, so I thought I finally would, then I forgot I had drawn it XD
So here they are; Boogle's little eyeball/cockroaches that she's sometimes seen with. They're basically just multi-colored eyeballs with cockroach legs, wings, pronotum, antennae and feelers. They can have more or fewer cockroach-y traits. But for the most part, they just look like eyeballs rolled around in dead roach bits : P They can be any species of cockroach, really... here, they are pictured with American cockroach (periplaneta americana) roach bits. They can be just about any size, but generally are about human eyeball-sized, with regular-size cockroach parts.
They have expressions which read in their irises/pupils. Such as the little knocked out one in the bottom, there. They can form a smile, frown, little "X"es when one is dead, etc.
Boogle may use them to juggle with, or as little helpers in her "magic" tricks
I like to imagine them making little peep noises when tossed up into the air. XD
