Creative problem-solving at its finest

Tom's father is so afraid of animals - even snails and butterflies scare him off - he won't come out of the house.

Tom decides to take drastic measures.
First he trains a polar bear and sneaks it into the house.
Then he smuggles in a tiger, a squid, a tortoise, a snake, two peacocks, three hippos and a small flock of flamingos.

His father doesn't seem to notice, but what will happen when he does?
