Octaman (1971)

Researchers in Mexico conducting experiments to measure radiation discover a strange little Octopus creature. After being unable to get funding for more research, the group turns to a promoter who hopes to capture a larger creature that he can make money off by charging people to see it.

After they capture some small creatures, a large rubber suited monster that appears to be an Octopus who walks on land, comes to get the little creatures back. The Octaman walks around a lot and waves its tentacles, but they are not capable of really doing anything so it isn't very threatening. In fact, it's a bit like a larger, less kid friendly version of the costumes for Sigmund and the Sea Monsters.

The film is often dark and there are many scenes where it's supposed to be night but it's daytime, or it's supposed to be day but

it's night. So there's some continuity issues.

The creatures eyes remind me of sparkly Candlepin bowling balls and it's mouth reminds me of the Salt Creature from Star Trek.

It's slow moving and can be tedious, but I love the Octaman costume. It's nice to go back to the days when monsters were men who wore rubber monster suits rather than CGI monsters.
