Cinema 4D file is ready to be rendered as in preview images. All materials, reflections, lights, scene and rendering setups are included in the project. OBJ and 3DS formats are exported from Cinema 4D, so no textures or light setups in there. Model was exported with disabled HyperNURBS, so object is in it's lowest poly count. You can apply smooth modifiers by yourself to get a subdivided mesh.

Yoshi is made off separate parts: Body, Eye and pupil, Tongue, Horn (3 pieces), Hat, Shoes

Model is in loops, so it's rigger/animator friendly.
