Under Carber Bay
In this chapter
The aqua lung lets Dizzy breathe under water; the bay's upper waters, then home with the dynamite and the wrench.
The trench drops Dizzy right next to the aqua lung for under water. With it, Dizzy breathes freely under the sea (Diving into the bay). Wade in and collect the upper waters' stars.

Without flippers Dizzy can't swim up to the far shore, so back to the near beach, Silver Stream and the village's ground floor. Leave the dynamite and the wrench lying at the ground floor's right end, next to the mushroom and the key.
