After collecting 30 quills from Shipwreck Creek (which has 10) and the first grand tome world, TribalStack Tropics, head to the center temple ruin and jump or roll up to the middle. There you will find Trowzer selling moves for 30 quils. Any of them help progress the game, but Sonar Shot will get you the Dr. Puzz achievement by activating the sleeping pillar behind Trowzer.
