What's the Matter with Horace?

Horace arrives at Wimzie's house in a foul mood. But Horace's mood changes as he introduces his imaginary friend, Spike the Mosquito, whose parents had a yelling fight that morning, to the gang. Yaya realizes that it's really Horace's parents who had the yelling fight. Later, Gratziella and Rouso argue, but they find a way to settle their differences, assuring Wimzie and Horace that fights and disagreements between parents don't mean they don't love each other.
