You know, I remember (and I'm sure many of you remember) when pets in Wizard101 were nothing more than cute adornment (NOTE: well, except for those pets that came with a card *thanks anon*!). Eventually those pets became much much more. And these days, what pet is complete without the awesome pet power Spritely!?
Yup! You start to see your pet break out into a dance and the next thing you know, you're getting surrounded by healing goodness and a cute little "HAI!" and you're filled with so much win!
I don't think I could even begin to count the number of times Spritely (or Unicorn or Fairy for that matter) has saved me OR how many times I've heard the expression "Good Boy" or "Good Girl" come from a wizard whose pet when nuts and cast a Spritely spell on them. In fact, it used to happen so much that we'd complain that we needed to shorten the animation casting time of the spell.
It's a wizard's best friend's best friend -- Spritely -- a truly awesome pet power.
