GMS v132 - Hyper Evolution

Oh, really? I had no idea. Do the demon/yeti/teddy bear pets do this? or is it all the pets after those?

Oops, I checked and the first Giant pet was the Koala in December, followed by the squirrels, demons (re-released with this skill), angels, and most recently Luti. The buffs themselves aren't that great either, best would probably be 5 all stats, 5 attack, 10 all stats, or 10 attack. I don't think you can choose which you get so you just have to wait for the 10 minute duration to run out.

Edit: Actually the Halloween pets had that skill too... so maybe I was wrong about being wrong xD
