1. complete a lot of levels in events
2. play golden cloud (the loot are snoutlings)
3. try to find a wealthy rogue and use strong birds to kill it because after 3 turns, he will go away
4. play dungeons (tip: upgrade your classes to Elite or Master so dungeons are much easier)
5. CHEAT!!!
Another way to get more snoutlings is play castle level (except Wizpig Castle.)
