Mook is a retro, unicase, bubble font; modular in approach but friendly in use.
There are a number of standard and discretionary ligatures. Try engaging discretionary ligatures and typing “I HEART Mook!” Wow, wasn't that fun?!
Mook is a bold but soft display font, perfect for T-shirts, posters and fliers, and if you're designing packaging for bubblegum, this is definitely the font for you.
