Mega Man Battle Network 3
Lan Hikari and MegaMan visit Yoka during a field trip from their school class. After viewing the zoo and returning to the inn for the night, the WWW NetNavi BeastMan hacks the zoo's system, causing the animal cages to unlock and the animals to go insane, trapping and attacking people. Lan and MegaMan jack in and navigate their way through the system's cyberworld until reaching the hacker, Takeo Inukai. MegaMan is able to defeat BeastMan and the zoo chaos subsides.
