Corrected entry: At the beginning when the trolls escape from the tree, the escape tunnel was destroyed by the Bergens' digging. When Poppy and Branch go back to Bergen town, the tunnel is suddenly unblocked.
Corrected entry: The Trolls have shown to be able to do things with their hair that should be impossible, like Poppy walking on her own hair as if they were stairs. So why couldn't they use their hair to pick the lock on the cage Chef puts them in?
Correction: Just because they can do impossible things doesn't mean they can do anything. Even if Trolls could use their hair to pick a lock doesn't mean they'd have the skills to pick a lock. I know people who can't pick a lock with actual lock pick tools.
Correction: It's possible the Cloud unblocked it.
