Gunther

Gunther is the first dog to appear on the Are U Super Cereal Channel. He is a Rottweiler/Pitbull mix.

Cereal had big plans for videos with Gunther. The first skit Gunther appeared in was Puppy ATTACKS Kermit the Frog and Elmo! where he appears to be attacking Kermit and Elmo. He also attacked them again in Puppy ATTACKS Kermit the Frog and Elmo AGAIN! He seems to attack Elmo the most. He also appears in the first three swimming videos where he swims with Kermit and Elmo.

At the end of Kermit the Frog and Elmo's Backyard Challenge!, Sean revealed that they won't be bringing Gunther with them when they move to Colorado for a number of reasons, one of which being that Gunther was not legally their dog (having been officially adopted by Sean's friend Alex a.k.a CptVideoGames), and Sean felt he wasn't ready to take on the full responsibility of having a dog. He also didn't think their new home was fit for an aggressive dog breed, despite the fact that Gunther was basically harmless.

In the video 'WE GOT A NEW PUPPY!', Sean stated on why they couldn't bring Gunther. Sean also stated that they have checked up on Gunther and that he's with a really good family.
