Block B are pokemon and they have been living harmoniously in their pokemon land, lazing around under the sun, frolicking in the vast meadows, having friendly battles with one another, munching on crispy poffins (pokemon food)....you get my drift. 

Their lives have always been peaceful, until one day, P.O  (a fire type pokemon and the youngest out of the gang of Blockemon) comes across a strange bottle of green liquid. His greedy, curious self downs the whole bottle down; and to his shock, he is transported to another world, where is has become this weird, two legged creature! He finds himself lost in the heart of Seoul, surrounded by weird beings who walk on two legs and speak in some strange language called Kolean? Qorean? Korean? He doesn't know.

The Maknae Pokemon is trapped in the human world, and now the other Blockemons have to do whatever it takes to bring him back to their world.
