Banjo-Kazooie
In Banjo-Kazooie, Bubblegloop Swamp's entrance is found on the fourth floor of Gruntilda's Lair, to the left of the Gruntilda statue, atop an orange hill. Its Jigsaw Picture requires 7 Jiggies to be completed and can be found near the entrance to Clanker's Cavern, through a tunnel that only opens once a switch on the room is hit with the Beak Buster. The only move taught by Bottles in this world is the Stilt Stride, which requires Wading Boots to be used. In this world, Mumbo Jumbo transforms Banjo and Kazooie into a crocodile.
