Wacky is a tall, purpleish blue hedgehog with white snout, chest and arms. She has long eyelashes, long, poofy hair and shoes/socks that nearly go up to her knees. She also has a woman-like shape and she can bend her limbs in a rubberhose sort of style.

When she gets possessed, her eyes are mainly closed with black goop leaking from her eyes.

In the EXEMania song "Deck the hogs" she wears fake reindeer horns, white scarf with red stripes and crosses.
