Robertryan Cory (also spelled as Robert Ryan Cory) is an American animator known for his work in character design for series such as "SpongeBob SquarePants" and "Secret Mountain Fort Awesome", the latter of which he co-developed and earned a Creative Arts Emmy Award for "Outstanding Individual in Animation" at the 64th Primetime Creative Arts Emmy Awards in 2012 for.
 He has recently worked as lead character designer on season 2 of "Gravity Falls", and is now working on Aaron Springer's forthcoming Disney XD series "Billy Dilley's Super-Duper Subterranean Summer".
Uncle Grandpa is an American animated television series created by Peter Browngardt.
 The series ran on Cartoon Network from September 2, 2013 to June 30, 2017.
 It is based on Browngardt's animated short of the same name from "The Cartoonstitute".
 "Uncle Grandpa" is also a spin-off of "Secret Mountain Fort Awesome", which was in turn a spin-off of the Cartoonstitute short.
 It is produced by Cartoon Network Studios.
The Cartoonstitute was a planned Cartoon Network project created by Cartoon Network's executive Rob Sorcher that would have been a showcase for animated shorts created without the interference of network executives and focus testing.
 It was headed by Craig McCracken (creator of "The Powerpuff Girls", "Foster's Home for Imaginary Friends", and "Wander Over Yonder") and Rob Renzetti (creator of "My Life as a Teenage Robot").
 39 shorts for the project were in development at Cartoon Network Studios, but only 14 of these were completed.
 Eventually, balancing 5 upcoming shows and adding another proved difficult and the project was scrapped.
 Of the shorts which were made, only "Regular Show" and "Uncle Grandpa" have been greenlit to become animated series (the latter was initially greenlit as "Secret Mountain Fort Awesome", before becoming a series of its own).
 On May 7, 2010, Cartoon Network uploaded nearly all of the shorts to their website.
 The only shorts not uploaded were "Maruined", "3 Dog Band", and "Joey to the World".
