It has a deep and involving story about these dudes

WiiWare's ThruSpace is in line for a 3DS eShop update, as a sequel has just hit the Japanese download service.

The trailer below shows what to expect, but anyone familiar with the WiiWare original should already have a pretty good idea: you fit different shapes through holes. The translation of the Japanese genre is "sprint slip puzzle", which is a pretty succinct description.

Like so much Japanese eShop content there's no word on when we'll see it leave the Land of the Rising Sun, but we'll keep you updated.
