Put your ING (ingredients) into the blender (2 maximum) and then click it. Then press on a cup and press pace. Then, you choose the size, and KERBLAMO! Smoothie. To make more than 1, press space after choosing size and letting it pour. P.S. The Pokemon just gives you hints, some useless, some useful.
I give credit to My friend for inspiring me to make a smoothie maker! If you find any glitches or bugs, write them in the comments, and I'll fix them ASAP!
