Naughty Nature  
- Shell Smash  
- Waterfall  
- Sucker Punch  
- Ice Beam

Notes: Huntail niche lies in the combination of Shell Smash + Sucker Punch. Huntail stands out from other physical Water-Type attackers due being immune to burns if using water veil or abusing Swift Swim + Shell Smash to become a fearsome weather sweeper and runs Ice Beam as a lure set for physically defensive grass types such as Tangela. It prefers White Herb over other items to preserve its bulk and give it more opportunities to set up against foes.
