Bubbloid

From Speedsolving.com Wiki

Bubbloids are a series of puzzles, similar to cuboids, except that they are corner turning. The name "Bubbloid" comes from Tony Fisher's original 4x4x5 Bubbloid puzzle. They include the Redi Cube, Dino Cube, Tony Fisher's Bubbloid, and more. Unlike cuboids, the outermost layers of bubbloids, which are the corners, are not able to turn unless the puzzle is modified in order to allow the corners to do so.
