Watermelon is a character who only appeared in Orange of July. He is large and Orange mistook him for Godzilla or an Orange-eating lizard. Watermelon was killed because Grand Finale flew into him after he was lit by Orange and caused them to explode. He later re-appeared in a flashback in Happy Birthday, when Orange was trying to remember what he always wanted for his birthday that was a Wii Pony.
- Like Avocado (Lizardberry), he is mistaken by Orange for a lizard.
- He is the first watermelon in the series.
