Sorry bandits, Jelly really can't be stopped.
And for a moment it felt like that monster was sent by someone to aid her. It'd be nice if that was the case- for a certain monster tamer to still be alive and helping from the shadows.
The tree monster was an unexpected bonus. After a couple more serious chapters, this was a pretty funny curbstomp ("Was that a rock? Oh well, just disintegrate it")
The bandit was actually saved by the evil mastermind (ok, middle management at most). Jelly's casual boulder-crushing fist would have turned him into a mangled mess.
