Full disclosure, Marill is one of my favorite pokemon of all time. I grew up in the era when the playground rumors (and even some official Topps cards) called it “Pikablu.” I fell in love with it when it first appeared in “Pikachu’s Vacation” and thought it was a cute companion for Tracey, who being an artist I could relate to. I still have a fair collection of Marill goodies~
I also went somewhat viral back in the day with a BellyJet Azumarill back when it had just become a possible combination. I remember being so disappointed in gen 4 when I saw it could learn these two moves, but never together. Of course now it’s a pretty common strategy so it’s nothing special today.
