The Talking Watermelon

The Talking Watermelon (referred to as "Watermelon") is a watermelon that appeared in the episode "Heatwave."

Physical Appearance
The talking watermelon is an average watermelon with a face casually drawn on with a marker or crayon.

Personality
The talking watermelon ironically does not speak. However, when Hank suffers from heatstroke, he hallucinates the watermelon speaking to him.

He appears to be a spy, as he has watched every episode of “Ron Spyman, Undercover Agent”, and knows the Landlord's thermostat passcode (1-4-9-5), which is coincidentally how much the enemy barber charged Spyman for his moustache trim in the season finale of that show.

Trivia

 * His face resembles the face on a paper bag in My Talking Tom.
