The day the player and their partner came to Lively Town, Krokorok tried to mug them, but the player, their partner, and Krokorok were trampled by the Expedition Society's Buizel, Archen, and Bunnelby chasing the Expedition Society's Swirlix. Afterwards, the three got up. Krokorok continued to try to mug them, but the three were once again trampled by the same Pokémon. When the three got up, Krokorok gave up and went into Café Connection.
The day after the player and their partner joined the Expedition Society, Krokorok tried to mug the player and their partner for the second time, but stopped when Buizel defended them. When Krookodile was near, Krokorok told him that the player, their partner, and Buizel had been bullying him. Krookodile told them not to bully Krokorok any more, and that if they did, he would deal with them. The two then went into Café Connection.
Personality and characteristics

When spoken to when en route to the harbor with Archen:
"(...Where are you, Mr. Krookodile?!)"
