[DeepL Translation - needs review] Elephant went out for a walk. When he met Hippo-kun and asked him to go for a walk, Hippo-kun got on Zo-kun's back. When he met Crocodile-kun and invited him for a walk, Crocodile-kun got on Hippo-kun's back. Finally, when they met a turtle and the turtle got on the back of the crocodile, the elephant could not bear the weight and fell into the pond. The humorous interaction between the simply designed animals invites children on a delightful walk.
