Urn your keep
As well as the village store, you can spend your gems at Tuki’s shop. She can be found hiding in urns within certain stages, selling rare potions and transformations, Shantae can become a fruitproducing tree or assume the form of a jug of gems if she’s low on health or funds respectively. Best of all, however, is the Blobfish transformation. In practical terms it’s just about useless; for comedy value it’s all but essential.
