Sci-fi, YA, Animorphs knock-off, 90s

[morivoveso]

I remember one christmas in the mid to late 90s asking for Animorphs books and nothing else. I ended up getting books about kids who could turn into things instead of animals. I ended up throwing them out, but recently remembered this event, but not the name of the books. I never read them as I was so disappointed, so I don't havea lot to go on, and google has been no help.
