Happy Happy Clover

both are kids shows feature humanoid rabbit main cast (Happy Happy Clover have other animals too but Zenryoku Usagi only have rabbits) that teach the kids several lessons in a fun way Zenryoku Usagi is quite focused on "work" theme and also some of the episodes of Happy Happy Clover are the same 

Animals living their lives in the forest. Both animes are fun and more focused on children. 

Both Clover and Hakumei are extremely cute following the everyday life of little existences in the forests. In Hakumei's case in the forest and cities there live both animals and little humans (about nine centimeters tall). Where as in Clover there's mostly animals only living in a forest. Most of the episodes in both series contain two short stories about what happened someday to them. Everyone is nice and kind so they have a lot of fun times together.  

Clover and Maya The Bee both act very similar such as being curious about the world around them and both have a theme about friendship and helping others. Like Happy Happy Clover, Maya The Bee also deals with a similar topic about how most animals are scared or humans and find them means but both characters try to convince the animals that not all of them are bad. If your a fan of animals,wildlife or even an anime with a "Slice Of Life" setting then you will enjoy this anime.  

Both are about a magical world replete with happy characters, light-heartedness, warmth, childlike innocence, and a carefree joy.  

Both Happy Happy Clover and Hamtaro are about cute and furry animals and there adventures.
