If you don't have Toon Barrel Dragon or want to play another big Toon monster instead I would recommend Toon Ancient Gear Golem. I run one myself because 1) I love Ancient Gears and Toons. 2) Its stats are bigger than some popular boss monsters and the effect makes it safe to attack directly without having to worry about DMF or WoD.
Problem with that- Toon Ancient Gear Golem needs to be normal summoned, can’t attack the turn it’s summoned, abs is so prone to removal that it’s never worth playing
Toon Ancient Gear Golem can be Special Summoned unlike its original counterpart. Also, it's less prone to removal than any other Toon. I'm not saying it's an amazing card, but it's far from "never worth playing".
