I decided to add the "Bad End" tag, as while poor Sagume isn't visibly suffering or anything, this image is clearly referencing the bad ending of the original Pikmin game (in which Captain Olimar, who Sagume took the place of here, becomes a Pikmin himself after failing to escape. Er, a Doremin, in Sagume's case).

With this in mind, I few like it should be in something like the Honey Trap pool or something (as that's the only pool I can think of at the moment). Since while very cute, this is clearly a terrible fate for Captain Sagume, who just wanted to go back home to the moon...
