GMod Tower has a Fancy Pants trophy, which was never given to backers in Tower Unite since the developers didn’t have permission to put Fancy Pants Adventures content in the game. Now that there’s a Fancy Pants plush in the arcade, though, I think it’d be really cool if it was re-added somehow.
Assuming the trophy wouldn’t be given out to the small number of players with the GMT trophies, it could just be another arcade prize, or an extra item you get if you buy the Fancy Pants plush. It’d also be a fitting alternative to the ultra rare Starfox trophy that you could get from Spin-to-Win in GMT.
