Palossand is a large sandcastle-like Pokémon with two accessory towers acting as arms. A gate-like tunnel acts as its mouth. The towers have a series of windows and on the center tower are two eyes. Several shells decorate its exterior, especially on the main body. The shovel that sticks out of its head spins when looking for prey.
Palossand controls adults into making sand castles that provides camoflauge and raises its defenses. Unlike Sandygast, it can replace lost sand by itself. It is said that its revolving shovel acts like a radar. Palossand drags small Pokémon into its body to steal their life force. It swallows them in a vortex nearly instantaneously leaving only their ill will behind.
