Ok Gunter is definately not a normal penguin. In fact I don't know what he is here are some clues to SOMETHING about Gunter

  • Marcelines Dad said he is the most evil thing he has ever seen (Could indicate something)
  • HE gave birth to a pink (Ice King asks Gunter why he didn't tell him ????)
  • Gunter likes to break things
  • Even Marceline has a Diary full of secrets about Gunter

Mabue Gunter is being contoled by the Lich.
