Stretchmo is a 2015 puzzle-platformer developed by Intelligent Systems for the Nintendo 3DS, and the fourth entry in the Pushmo series. Released under the names Fullblox in PAL regions and HikuDasu: Hippa Land in Japan, the game adopts a free-to-start model in which the tutorial is available at no cost and additional level packs must be purchased separately. Building on the pull-and-push block mechanics established by its predecessors, Stretchmo introduces two new elements to the formula: enemy characters that complicate navigation, and platforms capable of expanding outward, adding a fresh layer of spatial reasoning to the series' signature three-dimensional climbing puzzles. The game's content is divided into themed collections, allowing players to acquire only the packs that interest them rather than purchasing the full game outright.
