Going to assume they're eating a tiny pizza off of one of those three-legged pizza savers (since that would put them in an adorable Goliath beetle size range), and not from a real dining room table (since that would put them in an alarming Honda Element size range).
My thoughts exactly, they're enjoying a tiny pizza on top of a little pizza table.
to be honest i didn't actually think about scale at all lol but I'm in favor of this interpretation. Just some cute lil small bugs 😍. Not sure why the pizza table is brown but maybe eggbug painted it to look more like wood bc he saw a lot of humans seem to use wood tables
