Minions Thirsty Coloring

You control a paintbrush with your mouse. The game presents you with a black and white line drawing of a thirsty Minion, usually holding an empty cup. Your job is to fill in the sections with color. You select a hue from a palette, then click and drag over the areas to paint them. The challenge isn't really difficulty, but patience; you try to stay within the lines to make the picture look neat. The goal is simply to complete the coloring page to your liking. It feels like a calm, straightforward digital version of a coloring book.
