Uruno, a failure of a wolf, is currently traveling to find himself a new place to call home; but upon chancing across a rabbit, he attacks it only to realize that this particular rabbit is stronger than any predator! Soon afterwards he discovers that this entire forest he has come across is home to similar 'useless animals' that are atypical of their species. He decides to stick around when he meets his love interest in the form of a clumsy cheetah, and with his new friends, he meets the rest of the animals in the forest, causing much hijinx and fun in the process!
As the mighty star fleet of the planet Keron prepare their invasion of Earth, Sergeant Keroro and his elite team of commandos have been sent to infiltrate the enemy strongholds and gather as much intelligence as possible. However, it seems even his extensive military training is no match for the forces of Earth, as he is discovered and captured by the two middle school siblings, Fuyuki and Natsumi. Submitted to the rigorous torture of housework duty, the amphibious Keroro must now bide his time, covertly locate his squad-mates, and resume his mission of conquest!
As strange as it may seem, I feel that these two series have a reasonable amount in common. Both feature cute little creatures as the main protagonists and have a lot of comedy in them. Also, while the title suggests that the animals in Damekko Doubutsu are useless in their own ways, the aliens in Keroro Gunsou are also pretty useless in their own pursuits. If you enjoyed the comedic failings of the protagonists in one of these series and want some easy-watching and lighthearted entertainment, then it would be worth trying the other.
Asialand City is a bustling metropolis that is under attack! Strange monsters fill the streets, and heroes are needed - enter the Relaxation Combat Team Valerian! Comprised of three girls-turned-bunnies, the Valerians do whatever it takes to put a stop to the Stress Team - a group of evildoers who turn people's stress into monsters! From ramen monsters to beyond, there's nothing that Relaxation Combat Team Valerian can't handle!
Both short and sweet, each episode is a self contained story that doesn't really add much to the bigger picture. Sweet Valerian and Useless Animals both leave you with a sense of wonderment at what you've just watched, and why you're reaching for the remote to put on the next episode.
With not a whole lot in common storywise, or character-wise, I make this recommendation purely because they are both a good way to spend a few minutes of time and will leave you with a (bemused) smile on your face.
Need a job done right? Call the Zenryoku Engineering Company! Staffed by hip-hop loving boss Oyakata, aggressive Ojou, babysitter-turned-worker Minarai and a variety of other motivated rabbits, Zenryoku Engineering Company lives by a simple motto: do our very best! From finding old fossils to building a bridge to help a young rabbit find his way home, there's nothing the team can't build or handle!
OK, so at first glance this may seem like an odd recommendation; one series focuses on useful construction bunnies, the other is literally entitled 'Useless Animals'. However, both of these series are light-hearted and motivational series. Zenryoku focuses more on building up confidence and completing a job to the best of your (possibly limited) ability, whereas Damekko Doubutsu looks at finding your rightful place in the world - even if you are a bit useless. If you liked the upbeat and cute aspect of one of these series then you may well enjoy the other.
