You have to use a "moonstone". It wont eveolve othervise.
I'm not to sure about level, but you MUST give it a thunderstone.
Sneasel can only evolve if it is holding a Razor Claw when it is leveled up at night (at any level).
Give Sneasel a Razor Claw and level it up at night. It will then evolve into Weaville.
