Maybe I'm the only one who feels this way, but I love, LOVE small things. I know many players feel like companions should be bigger so they can be shown off and easily seen, but I lean more towards the smaller, the better mentality. Besides, these pets are for my enjoyment, not anyone else's, and I'm an absolute sucker for tiny cute things.
So naturally, I adore the Magical Mini-Treats. :)
Here's just a comparison between a normal sized Amethyst Shale Hatchling (on the left) and the same companion who's consumed a Magical Mini-Treat (on the right). Ahhh, the adorableness is overwhelming! XD
