Objective 1: Clear the Vines
Smash the purple flower to release a beetle that climbs the vines on the north wall. This attracts the attention of the massive carnivorous plant nearby. When the plant bites at the beetle, it tears the vines away, revealing some silver LEGO blocking the cave entrance.
Equip Cyborg with his Demolition Suit and destroy the silver LEGO near the plant. Inside of the cave, there is a phase point. Have Martian Manhunter pass through it.
Objective 2: Clear the Vines, Part 2!
After passing through the phase point, you arrive on a ledge above. Use a laser to destroy the gold LEGO stone that you find there. Build the bricks that spill out of it into a beetle. This beetle then scurries off and passes through some vines blocking the path on the far right side of the level, revealing silver LEGO in the process.
Follow the path of the beetle and you come across a Batman prop. Smash it!
Batman Smash Challenge: 1 / 3
Continue to follow the path of the beetle until you arrive at the vines it passed through. Have Cyborg use his explosives to destroy the silver LEGO on the vines. Continue to the right and you come to a clearing where Saint Walker is being held captive. Once you rescue Saint Walker, he joins your party.
Objective 3: Save Saint Walker
First things first. Take down the goons and try to do so with ground finishers to complete the combat challenge. Once the baddies are dealt with, equip Cyborg with his magno suit and pry open the massive insect’s claws.
Combat Challenge: Finishers
The insect flies away, but wave after wave of baddies take its place. Take down all of the bad guys and the giant insect returns.
Before tackling the insect again, be sure to destroy the Batman prop in the nearby pool. While it’s easiest to access in free play with an aquatic character, it can be targeted from land with heat vision or lasers. The final Batman prop is located in the water to the right of the insect, once again, this can be targeted from land as well. Easy!
Batman Smash Challenge: 3 / 3
Equip Cyborg with his Sonar Suit and use his sonic blaster to destroy the wings of the insect. Build the bricks that fall from it into a lantern pad.
As Saint Walker, interact with the lantern pad to build a giant baby bird that attracts the attention of a larger one that picks up the insect and hauls it away, ending the level.
