Fizzle’s design is based off an eevee, which is heavily influenced by the fennec fox. Her ears would be big and very fluffy to keep the desert sand out.
Ari has bunny ears, could be floppy but I draw them with a more defined shape. They’re longer and upright.
Izik is a grey squirrel and has much smaller, frizzy widdle ears. They sit so cutely on his head bawwww<3
So there you go. Their ears are different, with varying degrees of fluffiness and other functions and I just can’t choose they’re all so dorbz.
