In the scene when the actors walk through the resort and pass a giraffe in diapers, the giraffes were filmed at the zoo, then they used that footage to put diapers on giraffes in post production. Giraffes never wore diapers.

In the scene where the actor rides the elephant into the middle of the party, the VFX team took still reference photos of the Asian Elephants in their enclosure at zoo.
The enclosure was a large sandy area with a pond and several enrichment toys. The elephants were photographed in the morning before the zoo opened. They used images of elephants and placed it in final cut with man riding him. An actor never actually rode an elephant.
