I've inherited quite a few interesting pieces from relatives who outgrew LEGO. Any idea what set(s) these came in? They don't have any numbers so I can't look them up on pick-a-brick or anything.
You have the following pieces:
These were used in about 10-15 sets during a brief period from 1995-1998, most of them in the Aquazone theme, but some made their way into other themes as well (e.g. Castle).
Those are modified octagonal bricks numbers 6037, 6042, 6043, and 6032.
The blue corner pieces (6043) are only from set 6190-1 Shark's Crystal Cave
The others are likely from the 2162-1 Hydro Reef Wrecker
