Robin the Frog (The Muppets)

According to Muppet Wiki, "Robin the Frog is Kermit's clever and kind nephew who sometimes feels unnoticed because of his small size. He likes to spend time with his uncle Kermit, Sweetums and the Frog Scouts. He debuted in the 1971 television special "The Frog Prince", as a prince-turned-to-frog. He also made a few appearances on The Muppet Show's first season, which included his hit song Halfway Down the Stairs. His relationship to Kermit, however, was not established until The Muppet Show guest star Bernadette Peters encouraged him to believe in himself by singing Just One Person. Robin also played Tiny Tim in The Muppet Christmas Carol, and also starred as a protagonist on the 2000 Playstation video game Muppet Monster Adventure."
