Mr. Men/Uncle Grandpa


 * Mr. Tickle as Uncle Grandpa (Mr. Tickle is the first Mr. Man and Uncle Grandpa is everyone in the world's uncle and grandpa so it makes sense)
 * Mr. Grumpy as Mr. Gus
 * Mr. Cool as Pizza Steve (both are cool triangles)
 * Little Miss Splendid as Giant Realistic Flying Tiger
