Jazz Jackrabbit in Lego Land
In the olden days, computer game companies used to release various holiday versions of their games. Jazz Jackrabbit, for instance, had two Christmas editions: one in 1994 and one in 1995.
The 1995 version had two planets. The first was called Candion, which appeared to be a world full of candy, lollies and icing sugar. The second should interest people here quite a bit: Bloxonious, which was a world made from LEGO BRICKS!
