The Forbidden Forest (1-5) - LEGO Harry Potter: Years 1-4
Year 1, Chapter 5
Start off by destroying the wasp nest to the left. Next, free the student in peril a bit to the right.
The dog, Fang can dig on digging spots that you may have encountered earlier. Fang's character token is located in the lower right corner of the screen.
Shoot one of the yellow flowers here as they're part of unlocking a crest piece. Assemble the circular pieces on the upper right to form a raincloud. Control Fang and climb up the ladder. Dig the digging spot there to create another ladder. Climb up to find the second yellow flower. Finally, destroy the last flower under the beehive a short walk to the right. This will reveal a Yellow Crest piece. Continue to the right then use Fang to dig and reveal a subterranean path.
In the next part, use LuSo to clear the vine then shoot the obstacle until its cleared. Gather studs if you need; otherwise, continue ahead. Order Fang to dig the blue lego brick then shoot the webs to drop the other bricks. Before assembling it, switch to Fang then swim to the water. Have him dig in the middle mound to drain the water.
Backtrack and arrange the bricks and use them to jump up. Continue to the right then assemble the pieces to create a tree. Use WiLe again to extend its branches so you can reach the cave.
Green Crest piece - You need to look out for 10 dark stones. Destroy them using any dark arts character's Crucio spell. Watch the following video to learn more about the locations of these rocks.
Hagrid – Upon starting the third area, unlock the chest up north to get this character token.
Draco (Hogwarts) – After going up using the lego bricks, shoot the dark orb up north to get this token.
Blue Crest piece – After draining the pond, look for a locked chest in the lower right corner. Unlock it to get this piece.
Once in control, follow the ghost studs. After going upstairs, press B to change the direction of the stairs. Continue up and enter the door to continue.
