The sack version of Meow is really what she looked like when she was a younger kitty. She has since had a dye job to add more purple to her fur, but underneath, she’s only purple on her belly and paws!
Tremor of Moo and Friends makes his debut appearance on your stuff as his sack version. He’s normally much more yellow! Tremor wasn’t sure what he was until a DNA sample of a quill showed he was a hedgehog. Thank you, DNA!
