The PSN zoo has some unusual species.

The PlayStation Store is back, and it's brought with it two new releases for Move users: Under Siege and Lexis Numerique's Learning with the Pooyoos.

The educational title for young kids has already made several appearances on WiiWare, so it'll be interesting to see how it's made the transition across to more capable hardware and motion controller.

We'll be grading Learning with the Pooyoo in the near future, so if you're thinking of getting this for your little ones — or you're just really, really starved for a new PSN download — check back soon.
