In the wild, Sandslash are more offensive than their pre-evolution, Sandshrew, but are still mostly defensive by nature. They spend much of their time hidden underground in their burrows, and will kick up sand or curl into a ball to escape predators. It will also curl into a ball to prevent heatstroke during the high temperatures of the daytime in its habitat. Although it is known to regrow its claws and spines if broken or snapped off, it does seem to have habitual molting, for once a year the old spikes fall out, to be replaced with new spikes that grow out from beneath the old spikes.
When needed, they can perform a variety of techniques to attack enemies, including slashing at them, rolling at them while curled up, and even climbing trees and attacking from above. Although Sandslash are usually bipdeal, they are able to run on all fours.
- Despite being one of the few pure Ground-type Pokémon in the first generations, Sandslash did not learn any damage-dealing Ground-type moves via leveling up until Generation III.
- Although its species is the Mouse Pokémon, none of the animals it draws its design inspiration from are actually rodents.
