As we are in the middle of Double Pet XP, this seems like a good time to ask about players' worst pet fail. We all know the pain of a pet fail: You hatch your myth pet with a better myth pet in the kiosk, and you get balance talents. Or spell defy, 2 selfish talents, and power pip chance.
Mine is a tale of trying to get a utility pet for gardening. I found a unicorn in the kiosk, hatched it with my current gardening pet, and at adult, my new unicorn had incoming heal boost and extra intelligence. Thinking I could somehow convince the unicorn to become the pet I needed, I kept training. Extra strength, increased gold, and finally at mega, extra agility. I may have cried.
