Leslie is a supporting character in The Amazing World of Gumball. He is a delicate flower who is in Miss Simian's class at Elmore Junior High. He is Penny and Polly's cousin, as revealed in "The Flower." At the end of "The Awareness," it was shown that he is a dandelion.
Leslie is a pink flower who stays grounded in a blue flowerpot. He has a thin green stem coming out of the pot which he uses to move his head around and two long leaves extend from his stem, which are used as his arms. Green stubby roots pop out under his flowerpot, and he uses them as feet. The inside of his mouth is colored purple with a red tongue. In Season 2 onwards, he acquires eyebrows, like most other characters who received redesigns in the new season. In the early reel, Leslie's petals are colored baby-blue instead. In "The Awareness," it is revealed that Leslie is actually a dandelion when he removes his pink petals.
Leslie is gentle and, while he can be hyper and creepy (similar to Banana Joe), he seems to be intelligent and wise. He is also very effeminate and hangs out around the Treehouse Girls, possibly because Leslie is great at giving relationship advice. He plays the flute in the school band. Many people confuse him for a girl due to his feminine traits and his name. Most flowers are hermaphroditic, so it is possible he may actually befemale to some degree. He often says malapropisms (e.g., using "graceful" or "grapefruit" when he meant "grateful," or "condensation" instead of "conversation"). He appears to be a multi-instrumentalist; it is also revealed that he is quite the fashionista, to the point of having had a haute-cotoure "high fashion phase," and is obsessed with his image to the degree of narcissism and vanity. In "The Awareness", it's reveleaed that fee feels quite insulted when it comes to plant-insensitivity, and is afraid of being swarmed by bees.
