Oha Suta, a Japanese program, has revealed another new Pokemon for Generation V.

Not only does this show us some new backsprites, it gives us a new fish. Does it look familiar? It certainly
seems like a Luvdisc evolution, don't you think? Nothing is confirmed yet, though, so take it with a grain of salt. (It also looks like a candy heart with hands, but that's just my opinion.)
Filb.de is reporting the fish as being named
Mamanbō (ママンボウ), while the rocky craggy thing beside it is apparently
Gigaiasu (ギガイアス).
