Claude, being a smart man, has come to a conclusion about the Snorunts - which, if anything, could be summed up as 'Snorunts gonna Snorunt'. Essentially, he's decided that nothing any of them do really affects how the Snorunts are going to react to them, and they have no real control over the actions of these fickle pokémon! People will try to please them or drive them away, and get totally unpredictable results no matter what they do that has no bearing on how aggressive or conciliatory the approach is!

So, Claude's decided he's not really going to do anything special at all when the Snorunts arrive. Instead, he just treats them with the same casual friendliness he would treat any wild pokémon with while he goes about his day more or less like normal. Maybe he'll toss one or two a snack; if any of them seem interested in battling, he'll indulge them. But for the most part, he goes about his business, and lets them go about theirs with simple cheerful acknowledgment of their presence.

Part of him does kind of hope that simply being treated like normal pokémon might appeal to the Snorunts, of course. Maybe they get exhausted being sucked up to or being treated like the harbingers of ill fortune. Maybe they'll like being treated normally. But he has no real expectations; after all, there's no predicting them. They might be offended he's not paying them any special mind, either...
