Pocoyo
Fred (the Octopus) is a red octopus (although shown with only 4 legs instead of 8, as to make animation rendering simpler) who speaks in gibberish like Caterpillar, and is very fond of singing. He appears in random episodes, sometimes as a major character, sometimes in passing. As of Season Two, he is sometimes referred to as 'Fred'. He sounds similar to Pee-wee Herman.
