Your thoughts?

What do you think of this "water horse"? I mean, what even is a "water horse"? Why would someone come up with a name like "water horse"? Technically, any animal that moves swiftly could be called a horse, just think! "Cheetah horse", "Rabbit horse", "Pig horse", "Horse horse", "Salami and cheese sandwich horse"(they move swiftly when I'm jamming them down my throat). I just can't quite wrap my head around this name. When I watched this movie I was also very confused by the scene when old man Covington decided to join bon jovi on his tour around the world, shouldn't he have stayed and helped take care of the "water horse" with poor little Joey?! Why did he leave his family in the sticky mud of poverty with only a "Water horse" that isn't even a horse?!!

And I DID see this movie! I did I say!!!!!
