Shellder — every printing, every price, every gap.

Its hard shell repels any kind of attack. It is vulnerable only when its shell is open. The shell can withstand any attack. However, when it is open, the tender body is exposed. It swims facing backward by open­ ing and closing its two-piece shell. It is surprisingly fast. Grains of sand trapped in its shells mix with its body fluids to form beautiful pearls. Clamping on to an opponent reveals its vulnerable parts, so it uses this move only as a last resort.
