Winter is over and the forest animals are enjoying the first days of spring. The cuckoo discovers a large egg right next to the Easter Bunny's den. The animals want to persuade the Easter Bunny to paint the egg, but suddenly it cracks and a baby crocodile hatches from the egg. “Mama, Mama!” Kroki calls anxiously to the Easter Bunny. After some hesitation and because it is already getting dark, the rabbit decides to protect Kroki and to take him to the zoo the next morning.

But the rabbit doesn't know where the zoo is and time is pressing. After all, Easter is just around the corner! It is thanks to the friendly rat, the clever tomcat and the remorseful fox who stole the crocodile egg that Kroki gets to his family safely and the Easter bunny is able to hide the Easter eggs in time!
