紫禁城

紫 = 此 + 糸 : Zorro (z) needs some more special effects dust. To make it, he crushes a few amethysts (紫) in the space station (Ø3) by stomping on them with his boots (此). He then crafts a few bags out of a silken scarf (糸) to store the dust in.

禁 = 林 + 示 : There's a small forest of two Christmas trees (林) in front of the encampment ((e)n4). Although there's a sign clearly stating that it is forbidden (示) to touch the trees, Joan of Arc (ji) set up her guideon (示) so that it is supported by the two trees and she can practice pull ups.

城 = 土 + 成 : Again Charlie Chaplin is unable to exit engine. There is a wall of dirt blocking the entrance, and a progress bar showing that it will be removed soon, but the bar seems to be stuck.
