Mini Diamond Cookie Cutter is an A-Grade Treasure that was released for April Fool's Day 2015. Its ability is to make the Cookie smaller. The treasure effect can be stacked - when all 3 of this treasure were equipped, the Cookie would be so small and hardly visible because he/she would be smaller in size than a jelly.

Treasure is available from Great Treasure Chest and Supreme Treasure Chest from 1–6 April 2015 and 1–8 April 2016.

Equipped EffectEdit

Honey, I shrunk the Cookies! But wait! They're much cuter bite-size!
