Ni No Kuni 2 - Higgledy Gaggle Trophy / Achievement Guide - Awarded for getting a set of matching higgledies! [Bronze]

For this you must equip 4 higgledies with the same type of head accessory. You'll notice some higgledies have horns on their head, others have bones, sunglasses, hats, leafs etc.
Simply cook up all higgledies at the Evermore Higglery and go find all Higgledy Stones (trophy "No Stone Unturned"). Then you'll have plenty of choices.

When equipping 4 higgledies with the same head accessory you'll see a yellow text "Higgledy Gaggle!" on the screen. It makes the attacks of your 4 selected higgledies stronger.

The easiest 4 higgledies are (can all be cooked):
Pib the Peregrinator, Gyre the Flyer, Abradab the Aviator, Cummerbund the Clement.

Cook them, then equip them, trophy unlocked! You must research better Higgledy Cookbooks first.
