Terror a Mitad de Camino

Lois Lane and Clark Kent are sent to cover a circus (for some reason). They separate to cover more ground. While Lois is watching a show in the Big Top a HUGE (and very fierce-looking) gorilla (or ape) is accidentally let loose.

He proceeds to wreak havoc and, in the mayhem, other animals escape from their cages. Lois saves a little girl from the huge gorilla (or ape) but then it goes after her? Can Superman save her and the circus?

Very strange Superman cartoon. For once he isn't battling mad scientists or creatures--just animals. Also it seems kind of strange that he has trouble beating a large gorilla (even though it IS huge). And he doesn't even show up until 6 minutes in (this is only 8 minutes long). Still, it's pretty good.
