Killing low levels with Summon bags = abuse, what?

Summon bags are there to spout off the occasional round of chaos, panic, and confusion in towns and such. In short, they are there for fun and comic relief. I've set off a Showa Boss Bag before in Henesys and watched the tombstones fall like a cool summer's rain. I've unleashed aliens, toy robots, teddy bears, a King Slime, and even a Jr. Balrog as well when a crowd gathers and/or people are AFK and have their guard down. Plus I always watch for the people that could kill stuff and only unleash the mayhem when maximum damage, chaos, mayhem, and confusion could occur.

I only wish they had high level boss bags for Papulatus, Bodyguards A and B, Leviathan, and other stuff that can't be so easily killed. I'd love for them to have a Lyka Summon Bag. Oh the fun I could have with those.
