The boy, his older sister and his younger brother set out on a mock safari - for Hedgehog, while their parents try to pack the car. Little do the kids know that Spider has second-guessed their efforts to track down the elusive prickly animal. Every tactic of the hunt is foiled until they are sent packing.
The boy accidentally opens his hamster's cage and lets him out. The unfortunate creature finds he's sharing a dangerous world with the household cat who looks on him as an excellent supplement to dinner. Luckily, Spider sees the hamster's plight and helps him to escape the kitten's claw and return to the cage.
The boy, his older sister and his younger brother decide to have a concert party. They dress up their favourite animals and give them musical instruments. Their fantasy comes to life as the crocodile becomes a rock singer backed by Hedgehog on the lead guitar, Frog on the saxophone, Panda on piano, Hamsters as backing singers and of course Spider on the drums.
