Skelesnails walk relatively slowly, but will jump to attack from a distance and can do a fair amount of damage to players early in the game. They may also retract into their shell, making them temporarily impervious to damage.
Skelesnails are a good source of money and experience early in the game. While the Tar Skull provides slightly more Talons and experience, the Skelesnail is much easier to strike and is often found alone, while players fighting Tar Skulls will also be harassed by Maggots. The Skelesnails also appear in close proximity to Fire Eyes' Village, allowing the player to retreat to heal and resupply when needed.
