Seahorses Are Sold Out

Mika's father works from home and he's very busy! He can never find time for swimming trip he promised. So Dad allows Mika to choose a pet from the store while he finishes the project--something quiet like a mouse. And so begins a wonderfully turbulent story in which Mika brings home one animal after another. The mouse gets lost so they need a dog to find it. The dog is followed by a seal, then a penguin. How many animals can come to stay before Dad notices?
