Soooo Volcano's backstory is basically Plant and Earth were normal Wubbox until they both saw some strange portal open in their realm, it was as if the mysterious portal was calling them. Earth grabbed Plant's arm and dragged them into the portal, they were turned into cats as soon as they set foot on the mystical grass. You probably know how Volcano was born now- I KNOW WUBBOX CAN'T BREED BUT THEY WERE HALF CAT SO I MADE AN EXCEPTION- and thats why Volcano is a kitten-wubbox who is half Plant and half Earth!
