I totally get it! I have the same problem with these animals - they have clothes on and look too humanoid. I really don't want to give away 3 spaces in my forest for them when I have really cool animals in storage that I'd love to hatch. I will probably never ever hatch Hansel if I go that far in the Storybook.
I haven't decided what to do yet... But I haven't regretted not getting Wild Wondercat for a second and there are always more Storybooks to come...
