Put it at the start of the scene, just as Seto Kaiba enters, then follow with the Anime Ahh reaction when the monkey fails to appear, and close with JoJo To Be Continued once the demand hangs in the air.

This is a 1.2-second Brazilian Portuguese voice line in which a speaker announces, in Portuguese, that he came to see the monkey, with Seto Kaiba named alongside the line. The blunt, matter-of-fact delivery makes the absurd request feel funny and slightly confrontational, like a challenge issued at the door. It lands best as a quick, knowing reaction rather than a long setup.
