4th Gen Primo

[Palamon]

This guy, in case anyone is going to ask, "Who's Primo?"

Anyway, in HG/SS, a man named Primo will give you special PC wallpapers, and Pokemon eggs if you say phrases to him through the "easy chat system", however, it's all random and depends on your trainer ID. I'm not going to link the secret phrase generator, but there are a few you can use to generate your secret phrases to let you get these free eggs and secret wallpapers. The eggs you can get are Mareep, Slugma and Wooper eggs. As for the wallpapers, I don't know. Google filb . de secret phrase generator for further help.

To those who have done this before, which Pokemon egg did you end up going for? I input the codes for all three eggs at one point. This isn't so much a feature as it is an easter egg. It's a pain having to have a phrase generated, honestly, so I rarely bother with it.

First time hearing about this guy... or so I thought! Looked him up on Bulbapedia and, turns out, he's the PokeDude from Teachy TV (which I used to watch often as a kid and tried to replicate it on my own)!
Another fun fact about him: he is the grandson of one of the most known Pokemon NPCs - the old man in Viridian that shows you how to catch a Pokemon!
