Eggos mods aren't my cup of tea either, though I know they're featured in the series. I haven't seen the game in person yet, but I think a large Mind Flayer would be a great mod. From what I can see in the pictures, perhaps it could be placed in back, right. Maybe it could be built on spring(s) so that it appeared to move when balls are in the pops, or some other target is hit.
