>>55138753The pattern for many Pokémon giving extra stardust is if they hold a valuable item in one of the main series.
The amount of stardust they reward reflects the value of that item.
>Meowth (Kanto and Alola) - 5% chance to hold a nugget in FR/LG>Paras - 50% chance to hold a tiny mushroom, 5% chance to hold a big mushroom in multiple games>Shellder - 50% chance to hold a pearl, 5% chance to hold a big pearl in multiple games>Foongus - 50% chance to hold a tiny mushroom, 5% chance to hold a big mushroom in multiple games>Morelull - 50% chance to hold a tiny mushroom, 5% chance to hold a big mushroom in multiple games>Trubbish - 1% chance to hold a nugget in Black/White>Staryu - 50% chance to hold stardust, 5% chance to hold a star piece in multiple games>Shroomish - 50% chance to hold a tiny mushroom, 5% chance to hold a big mushroom in OR/ASThis doesn't apply to all Pokémon though.
Other species that give bonus stardust include Delibird, Sableye, Chimecho, Combee, and Audino, but they do not carry valuable items that translate to a high stardust catch bonus. They probably have another thematic reason for the bonus, such as Audino's famously high EXP yield for power-levelling in B/W.
Catching a Galarian Meowth does not provide a stardust bonus like the Kantonian or Alolan variants.
Dwebble arguably should give a stardust bonus, because in B/W it has a 1% chance to hold a rare bone.
Audino notably applies its stardust bonus differently to all other bonus Pokémon.
Instead of having a base stardust of 2100, it has a base of 100, and adds 2000 after all other active bonus effects (event, weather boost, star piece, etc).
A double stardust event will award 2200 when catching an Audino as opposed to 4200.
Cloyster by comparison, has a base reward of 1200 stardust, so that will double to 2400.
