The Nidoran, whom shall soon no longer only be referred to by his species name, steps right into the jaws of a feisty Trapinch! It seems Nidoran is too scared to keep fighting after almost having lost its leg...
... but unwilling to disappoint you again, it regains its focus and sends the wild Trapinch spiraling! Just far enough that you can still reach it with a pokéball. Congratulations!
You and Trapinch carefully get to know each other. It's not always easy; Trapinch seems to interact mostly by biting. However, thanks to your immense patience and very tough extra gloves, you have soon befriended the pokémon which you aptly name Good Boi.
One day, you traverse a route with a particularly rocky landscape. Suddenly, from behind a particularly rocky rock leaps a blue creature, poised for attack!
It is a wild Riolu!
You test the waters of the new bond between yourself and Good Boi, but ultimately the Riolu manages to outwit and evade the jaws of your pokémon. Leaving Good Boi in a sorry state, the Riolu blows raspberries at you before it takes off behind the particularly rocky rock again. Good Boi might need some careful attention now to not feel like muk over this humiliating defeat.
