Many years ago in the Hidden Kingdom, animals and humans
lived in perfect harmony until an evil trickster named HighRoller
arrived and fooled the animals into thinking humans were their enemies.
Chaos reigned in the Hidden Kingdom until Commander ApeTrully formed a
task force called Big Green to reunite the animals and humans while
fighting the forces of High Roller and the Zebra Brothers.The storyline in a typical episode follows a formula, although the
formula varies and several episodes depart from it: Commander ApeTrully
goes on a mission to the castle of an animal kingdom to make peace and
ask its inhabitants to join Big Green, bringing a gift of gold as a
token of goodwill. The animals generally dismiss the gift, and usually
capture ApeTrully who calls for help from First Squad. Members of First
Squad (usually everyone except Mr. No Hands, who does come along on
occasion) deploy by descending through a maze of tubes and landing on
turtles fitted with tank treads, and then are launched through a tunnel
and out over the water. When they arrive where ApeTrully is being held, a
battle or contest ensues, during which special talents or abilities of
the animals are revealed, often something based on their nature. After
the battle or contest, the animals usually concede to First Squad's
skills saying through translation by ApeTruly (unless the animal rulers
can talk) that they would be honored to join Big Green. After joining,
the animals often are assigned a particular duty at Big Green based on
their demonstrated skills, which may help solve a problem introduced in a
subplot.The show is very loosely based on ancient Chinese novel the Water Margin focusing on the exploits of First Squad and Second Squad.
