What do you mean by 'on-theme'? How does a story about a multigenerational Colombian family who receives magical gifts from a miracle and then tries to defend their family and magic fit a theme about conservation and how animals live and behave? How does a story about an archaeologist who tries to defend historical artifacts fit a theme about conservation and how animals live and behave?
I’m sorry, but just adding a random animal to these completely different stories doesn’t make them a good fit for the park’s theme. If that’s your logic, what would be your argument against a Doctor Strange ride at Animal Kingdom where he uses the Time Stone to save endangered species? That kind of thinking is why all parks now look and feel the same—they're just Six Flags parks with no real theme...
