Lionel

Incredibly grumpy. Can never appreciate a joke and gets mad at the slightest teasing. When he gets mad, smoke comes out of his ears from his lungs, regenerating them. King of Grumps in Grumpsburg. Also unbelievably performative.

Lionel is sooooooo grumpy

lionel mentality

A model railroading expression generally used to describe unprototypical operations,extremely toy-like,a real far cry from reality.

I don't like his setup. I think he has lionel mentality.
