Just watched it. Anime-original, here we gooooo!

I like that they brought in the two ladies this early. This episode was not as funny as the others though. The best parts are Saitama's complaint about the seaweed and hair effects and the blatant parodying of Hunter X Hunter (and other derivatives) with the city visit, the ranks, and the strange powers. Even the forest monster scene was screaming Chimera ants.
