My Main Squeeze

(Spoilers!)

2 Dolls are in the Hermits Hut

1 Doll on the boat suspended in the air, where his tapes where kept before the explosions.

1 Doll on the upper level, far right side, in the first part where you are "indoors" in wurmwater, whilst fighting pirates. (apartment block) - before you get to the bridge and lift taking you to the hermit.
