He's not pretending to be a fool, he is a fool. In general, Tim (from my au) is a shy, anxious, introverted mushroom guy. This dude lives in the autumn forest, where only mushrooms, mosses, crimson trees grow there, how to say, he is the master in this forest. And he has 1 older and younger sisters, 4 older brothers and 2 younger brothers. And his appearance is the same as the original Tim from "tankmen", but he just wears a red hat with white spots, similar to the hats of fly agarics.
