[Scripting Question] Side Quest

[Lazooor]

I'm trying to make a sidequest where a man ask me to catch a Poochyena, but I don't know how to script it.
I need to make it so that after I've caught a Poochyena, the man then asks if he can see the Pokémon.

Spoiler:

In the default starting town, Lappet town or something, there's a man in your house who does the same thing with a celebi. You could copy the script from there.

Thank you so much, I think it works now.
