Blue Caterpillar was one of Florence's creation. He was stuck in the basement of the Wonderheart Cafe for a very long time. He absolutely dispises Florence because Florence was an awful person. They have memories of every person in Wonderheart. They made a deal with Pluto to give their memories back if Plu ever found a way to get then out of the basement and fixed up. Now they sit in th basement waiting to be fixed. They watch the cameras around the Cafe for entertainment. And also pay the taxes
