I've been zapping my pet Romelus a few times each day, and it seems like every other day he's turning into either a normal experiment 404 or a chibi one...

Yes I understand the concept of "random", but honestly whenever I get a pet change zap it's into one of those two things, nothing else. Do I have (amazing) luck..? Is anyone else experiencing this?

This happens without me selecting the 400k experiment zap option.

404 Other Experiments Not Found

On a serious note, that does seem pretty strange. I haven't used the zapper since Morostide so I can't confirm this has been happening to me as well. If it isn't a glitch, hopefully you have some better luck soon! :)

I doubt it's a glitch. I had it once where, with the 400k option though, it zapped my pet into the same experiment three times in a row. I reported it as a potential glitch/bug and was just told that because it's random there's nothing that can be done and it's just 'luck of the draw' basically.

The experiments only one? Nope.
