>>55261741He's a charismatic liar who was hired by Blueberry Academy to motivate you to do those HECKIN' BBQs under the absurdist idea that you'll be rewarded with snacks that can apparently draw out extremely rare Legendary Pokemon.
Except because he only arrives after you capture Terapagos, who is henceforth on your physical person much like your bike dragon, you end up being able to completely benefit because Terapagos has the same mentality as a bright and optimistic toddler, one who completely and genuinely believes Snacksworth's tall tales and that all you need is that snack right there, and decides to help (You) out, either consciously or unconsciously, by summoning those Legendary Pokemon into the described locations around Paldea by drawing them in from other points in spacetime, much like how Hoopa is responsible for the many legendaries in ORAS, or how ultra wormholes are responsible for the many legendaries and UBs in Dynamax Adventures.
