I'm not sure, ill go check and edit this post accordingly.
EDIT: Koga's muk has sticky hold.
The new challenge is:
In order to evolve to Crobat, bankrobber must steal a sitrus berry from each of the elite four's signature pokemon.
Golbat doesn't need to KO the pokemon, just steal the item.
That means Golbat must steal an item from:
Wall's lvl 42 Xatu
Bruno's lvl 46 Machamp
Koga's lvl 44 Crobat
Karen's lvl 47 Houndoom
Lance's lvl 50 Dragonite
