Captain Toad and his crew, the Toad Brigade, are scattered around Lake Lapcat in Bowser’s Fury. Finding them will net you a Cat Shine.
Captain Toad and the Toad Brigade only appear in Lake Lapcat after you collect 50 Cat Shines and take down Fury Bowser. If you haven’t done that, they won’t show up, and you’ll need to continue finding more Cat Shines.
Toadette is on Fur Step Island by a tent, but she’ll be distressingly saying that her gang has vanished. You’ll have to find them hiding out in different areas before they’ll return to her. Once you find them, they’ll each give you a Cat Shine, netting you four total.
Captain Toad location
Captain Toad himself is on Scamper Shores, getting chased by some rainbow beetles on a small island. Knock all the beetles away from him, and he’ll give you a Cat Shine.
Blue Toad location
The Blue Toad is at the top of Mount Magmeow, off to the side. He’ll be in trouble with an ostrich pecking at him, so get rid of the monster and talk to him to claim the Cat Shine.
Green Toad location
The Green Toad is at the northernmost point of the map. You’ll need to fling yourself across some springs to reach him.
Yellow Toad location
The Yellow Toad is under Slipskate Slope. Use the Super Leaf to turn into Tanooki Mario and carefully float down under the bridge to find him on a ledge.
