[TOMT] Show or "Movie" That Played In a museum about two Alligator or crocodile

So, this wasn't just any museum, it was International Wildlife Museum in Tucson Arizona. Where it had this small set up like small movie "theater" were I guess you can see stuff, related to animals. Idk, I only went to it twice and one of the time it wasn't working. However when I looked the Museum up, I was kinda surprised there was no screen recording and there was barely any videos on you tube about the inside of said Museum.

Also take this with a grain of salt, I was a child when I saw said film. So I could get things wrong.

One time they played a film (?) where two Alligators or Crocodiles (this detail is important later). The main character brother wants to go somewhere. Main character is reluctant but decides to go. Even though it is dangerous.

Note, I think I recall they were babies or well very tiny.

After taking a risk the two brothers are swimming in dangerous waters. With fish that can kill them, unfortunately one of them spots them. Where the fish eats the brother where he said something about wanting his brother to carry on the journey.

The main character somehow end up in neighbor. Where he sees a pool and I think there water sprinklers. Yet, after a bit he decides this isn't for him. So he continues with his journey. Also I think he is grown at this point

Finally he makes it, I think the film (?) is almost at the end where he ends up where he and his brother wanted to be at. Where he meats his cousin is either a Alligator or a Crocodile. The two chat.

Basically at the end the main character decides to go back home and the two say the lines of . "see you later alligator" " in a while crocodile". Again I forgot who was the Alligator and Crocodile.

The style, was pretty realistic. Like I am sure there could of been use of real animals but I no doubt believe they could of used cgi. Heck even animatronic to get certain shots.

Also I wouldn't doubt it wasn't made just for the museum , like they could of gotten permission to use it. I am just idk if anyone remembers it or not
