I remember Godzilla vs King Kong from 1962. Godzilla breathed fire on King Kong, and King Kong didn't like that so he reached down, ripped up a tree, and stuffed it root ball first down Godzilla's throat.
I remember as a kid seeing that on TV and getting upset and shutting it off when Godzilla started losing. I later found out that the US version edited the original Japanese one in which Godzilla won. Typical US propaganda!
Also, King Kong is like 50 feet tall and Godzilla is 300 feet, so he'd just step on him and move on.
