After successfully saving the forest once, Xiong Da, Xiong Er and Bald Qiang thought they could live a peaceful life. However, a mysterious force from the unknown depths once again disturbed the peace.
One day, a strange space-time vortex suddenly appeared in the forest. The strong suction pulled the unsuspecting Xiong Da, Xiong Er, Bald Qiang and some small animals into it. When they woke up from the dizziness, they found themselves on top of a huge interstellar battleship. This battleship is controlled by a group of machines from distant galaxies. They travel around the universe and collect the energy cores of various planets to maintain the survival of their own race. But for some unknown reason, their system malfunctioned, and they mistakenly regarded the planet where the forest animals were as an energy source collection target.
To make matters worse, the battleship's energy core is closely linked to the fate of the little animals in the forest. If the machine race obtains enough energy, the forest will disappear forever into the dust of the universe. To stop all this, the little animals must cooperate with the intelligent core of the mechanical tribe - Ava, a female robot with kind self-awareness, to search for space repairers scattered on various planets in the intricate interstellar channels.
Their first stop is a hot planet enveloped in liquid metal. The metal droplets here seem to be alive, constantly chasing the intruders. Xiong Da relies on his courage to open up a path for his partners on the hot ground; Xiong Er uses his greedy but fearless characteristics to look for possible clues in an environment full of dangers; Bald Qiang relies on his rich survival skills
