"Yog - Monster from Space" a personal Kaiju favorite.

The first Kaiju movie I ever saw on the big screen in 1970 at the age of 10 with kid brother in tow. Underrated, fun stand alone movie set on a tropical island with a "Space Amoeba" ( original title! ) beset by an intelligent space virus that transforms a squid, a turtle and a crab type creature into giants. This does not cross over with any other Kaiju movie or universe.
