|Best feature:||Ice breaker Strength|
|Best driver:||Captain Barnacles|
The Gup-C is a big, blue Gup with a large towline. It is Shellington and Dashi's favorite, with them being able to pilot it with some competence in comparison with the rest of the Gups. It looks like a blue whale. The towline is for pulling Gups out of wedged objects, for example, rocks. The window at the top is used for the icebreaker attachment. With the exception of Professor Inkling Octopus and the Vegimals, all the Octonauts have driven the Gup-C.
