you were a twisted... half. you could control your body, but sometimes something controlled you... You are a partner of Cosmo and Sprout. Cosmo has been helping you lately (Sprout isn't jealous, THIS IS NOT FRUITCAKE). and one day Cosmo was helping you deal with your problem, but you couldn't control yourself... and you scratched Cosmo's hand...
"OUCH! What's wrong with you!? Why can't you be calm!? Don't come near me anymore!!!"
and every time in the kitchen Cosmo didn't even want to look at you...Sprout saw this and tried to reconcile you, but all to no avail... and when you became almost 100% twisted you decided to go down to the VERY bottom floor to protect everyone... and when Sprout told Cosmo about this, he just... kept silent, but at Sprout's request they went looking for you...
