WildPokemon is a plugin to make mobs spawn in Minecraft like they do in Pokemon. Run through grass and every step you take has a chance of spawning an entity/entities of your choice (all customization in config). Also, increase or decrease the chance of mobs spawned in grass (also in config).
disabledWorlds: [world1, pvpworld] - Put in the brackets (each followed by a comma) all the worlds you DONT want to use WildPokemon.
enabledMobs: [chicken, zombie] - Put the mobs you want to spawn in grass (randomly picked from that list)
mobChance: 5 - The percentage that mobs will spawn in the grass. Recommendation: Less than 10 percent is ideal if you dont want mass-spawning. Setting mobChance to 1 will simulate Pokemon spawning the best.
Source in jar

wildpokemon.spawn - Players can see the spawn message and mobs will spawn in tall grass.
Note: 5 percent is still very high, make the chance of spawning 1 percent for a more realistic experience.
This plugin was made as a request based on the original idea from user PokeWillPower.
