Quick Scoop

The Frozen Walnut in Fisch is obtained by fishing at the Overgrowth Caves in the Northern Expedition area. The guides I found consistently point to the same spot, and several note that you just keep fishing there until it drops.

Extra note

Some videos mention a “Sparkling Nova Frozen Walnut” version tied to the Fabulous Rod quest, but the base location is still the Overgrowth Caves.

TL;DR: Go to Northern Expedition, enter Overgrowth Caves, and fish there with a luck- boosting rod and Aurora Totem.
