I have been searching for a movie that I saw when I was a child and I’m 57. It’s from the 50’s or 60’s. What I remember is that a boy finds an egg in a cave on the coast. He takes it to his grandfather at a circus or zoo. The egg hatches and out pops a 2-legged, 2-arm monster with a tail. It’s tiny and the boy plays with it at 1st but then when the monster grows and reeks havoc. I also remember the monster fighting a lion or a wild animal from the circus or zoo. Please help me find it. I would love to watch it and share my childhood experience with my boyfriend. Thanks so much! I look forward to hearing from you soon.
