The Day of the Dissonance — Alan Dean Foster

Clothahump, the wizard, is dying. All that can save him are rare medicinal powers to be found across the Glittergeist Ocean, past distant Snarken, Jon-Tom, the Spellsinger, sets out on the most perilous pilgrimage of his still-young career, armed with only his music-making duar and a reluctant Mudge, the otter, as his guide. Along the way he conjures up Roseroar, Amazonian tiger, rescues Jalwar, the ferret, and together they free Folly, the beauty, from bondage! Spellsinger and his motley crew press on, confronting a forest of Fungoid Frankensteins on the Muddletop Moors, a parrot pirate on the high seas, cannibal fairies in the enchanted canyon, and the evil wizard of Malderpot who poses the greatest challenge of all!
