Is the "Butterflytchi" a boy or a girl? If it is a girl, it could be Ura Memetchi or Ura Violetchi. For the boys, it could be Celebtchi.
Edit-Here's the Tama Zone chart for the V4.5. Notice there is no Butterflytchi there. Tell us if it is a character in there. They have names below each character, so tell us the name that matches the looks to your "Butterflytchi"
