Accompanied by Willi Weitzel from the TV show "Willi wills wissen," players explore different worlds, unlocking new levels, and uncovering interesting facts about frogs.

Ferdi showcases remarkable abilities, from jumping and flying to scaling steep walls. Players must follow the guidance of glowing fireflies to guide Ferdi's movements and collect hidden red fireflies to gain insights into various frog species. With simple swipe controls, players can control Ferdi's jumps, transformations into a flying frog, and swimming prowess to overcome obstacles and evade threats in the natural environment.
