In "Release the Krakenfoot", he made a return appearance, flying through the sky in butterfly form. However, he should have disappeared with the loop after Chick Magnet. The explanation for this is that once it became mutated, it technically became a monster. As explained in "Monster Stink", monsters are unaffected by the loop, due to the loop being a man made concept. This would also mean that Baby Theo is unaffected too.
