Okay, two movies.

both I saw maybe when I was 9-10, 18 now. I saw tem both on TV but I think they’re movies.

the first one featured giant lizards (not godzilla sized) but person sized. And they walked around attacking people. I remember one part where it ate a kids show I relieve while they were escaping.

The second featuring almost piranha like fish, but wasn’t any piranha movie. They could walk on land and I remember them walking through a forest to attack a person, attacking people on a boat and attacking an old couple.

I believe eve they could have been made around early 90’s
