None.

A couple of people get squashed by the giant gila monster. The people are shown being covered by a giant foot-shaped shadow. The giant gila monster also causes several wrecks some of which are shown burning. House damage caused by the giant gila monster is shown, and once the movie shows the giant gila monster breaking into a building while a party is going on inside.

None.

One of the characters smokes a pipe. Two characters are shown drunk. One of them is even shown drinking while driving.

The scenes with the gila monster was perhaps meant to be scary, and they might actually be scary to someone not used to seeing people threatened by giant creatures.
