Symblism of the Monkey in the Tweits

The monkey cage is where the Twits keep Muggle-Wump and his family imprisoned. The Monkey Cage symbolizes cruelty and slavery, as the Twits force Muggle-Wump and his family to stand on their heads for hours each day to learn tricks for their planned upside-down circus. Muggle-Wump desperately wants freedom for his family and for himself, and when Roly-Poly arrives, is able to gain that freedom when Roly-Poly finds the key to unlock the cage.
