No, that isn't an illustration for our fan-fiction novella about Tim Allen seducing dinosaurs: There really was a Home Improvement game for the Super Nintendo that sent Allen's character on an adventure across exotic landscapes, all the while grappling with a drill and shooting nail guns and Harry Potter spells at pterodactyls. Apparently the programmers were halfway through the game when they found out Home Improvement isn't that Spielberg movie set in a park.

Astoundingly, there's an explanation for this madness, and it has nothing to do with someone suffering a cocaine relapse: Tim is on the set of his show-within-a-show, Tool Time, when he learns that his special tools have been stolen, so he goes on a tour of various movie sets to recover them. As for why the presumably animatronic dragons and shit are trying to kill him, that's not explained -- it's just assumed that everyone and everything naturally hates Tim Allen.
