Time Baby

The  appears in the episode, "The Time Traveler's Pig". He is in the far future that Mabel and Dipper accidently transport themselves to. He appears to be destroying a city. In the credits, he forces Blendin Blandin to remove all anomalies that Dipper and Mabel cause when they messed with Blendin's "tape measure". Presumably, he is the leader of the Time Paradox Avoidance Enforcement Squadron. A document in "Irrational Treasure" said that a "time devouring baby is trapped in a glacier in Antarctica". This may be a reference to The Time Baby.
