Ekans pokedex

Pokedex data

Red Blue	Moves silently and stealthily. Eats the eggs of birds, such as PIDGEY and SPEAROW, whole.
Yellow	The older it gets, the longer it grows. At night, it wraps its long body around tree branches to rest.
Gold	It can freely detach its jaw to swallow large prey whole. It can become too heavy to move, however.
Silver	It always hides in grass. When first born, it has no poison, so its bite is painful, but harmless.
Crystal	It flutters the tip of its tongue to seek out the scent of prey, then swallows the prey whole.
Ruby Sapphire	EKANS curls itself up in a spiral while it rests. Assuming this position allows it to quickly respond to a threat from any direction with a glare from its upraised head.
Emerald	An EKANS curls itself up in a spiral while it rests. This position allows it to quickly respond to an enemy from any direction with a threat from its upraised head.
FireRed	A very common sight in grassland, etc. It flicks its tongue in and out to sense danger in its surroundings.
LeafGreen	Moving silently and stealthily, it eats the eggs of birds, such as PIDGEY and SPEAROW, whole.
Diamond Pearl Platinum	It sneaks through grass without making a sound and strikes unsuspecting prey from behind.
