Intro. In 1990, Willow, Max, Pete, Hoops and (your OC). They were tiny inside a huge "garden of scientist Wendell, having to fight and survive against huge insects but now everything has changed. 1992, two years after they became the normal size, they made a tribute to the scientist who took it from there:" Wendell. "But Wendell went crazy and ripped his head from his own lab friend, a super fun and cool robot called:" Burg.L " Soon this incident a purple explosion happened in the park, everything was dark, and when the five teenagers woke up were shrunken again, but this time .... inside the huge Brookhollow Park. Having to face new enemies, new insects and a sixth female teenager who had also been tiny, behind the explosion in the park. Good luck on your journey with your 4 friends from before !!!!
