Nuper Gummi is a cartoon vs. ornament texture pack with blocky and sharp edges. The texture pack works best in more open areas such as the default terrains in Minecraft. Crowded areas such as the one displayed in image below can make the world appear a bit overwhelming.
Other than that it’s a really nice set of textures if you enjoy cheerful and colorful textures. It was originally created for PC by LateGum but has now been ported to MCPE by migue_300.
