doing some maintence, thanks for your patience!
Rather than making a nest in one specific spot, it wanders in search of food after darkness falls.
Aridos evolves from Spinarak which makes it an easier Pokemon to get early game. Swarm and Sniper as two of the ability options make it more powerful either way, rather by increasing Bug type moves or just powering up critical hits. It can learn Toxic Spikes which is a great move, but its only available via an egg move. Considering its movesset has moves from many different types, including Psychic, Poison, and Ghost - it has pretty good coverage. It does have a few weaknesses though.
Note, you can always call Professor Elm with the Pokemon you are trying to evolve as first in your party. This was a feature that was added specifically to Polished Crystal. If the information on this page seems incorrect, please try calling Professor Elm.
