べるぜバブ - Season 1 Episode 17 Xalqada 17
Guudmarka: The Demon King sends Beelzebub some summer homework, containing a notebook which brings anything drawn in it to life. Next, Hilda brings Oga to Ishiyama High to collect prints of rare, powerful beasts, aka the delinquents, by whacking them with a giant fly swatter. During the chase, Beelzebub ends up planting several carnivorous Demon Plants, one of which grows into a massive giant causing havoc until Oga destroys it.
Faallo
The anime itself doesn't shine in any specific category, and probably some (few) parts/elements are "broken", but all in all it's warm/positive/funny. I didn't like much the first episodes but there weren't any hard reasons to stop watching it so I kept going => I didn't regret that decision - at around the first quarter I started liking it. The last episodes are, in my opinion, superfluous.
