Lockweeds - S1.E31

Florrie wants to go flying with Zoom Zoom, but Ferdinand needs her to help pick all the lockweeds - otherwise they will grow around the castle and trap everyone inside! Florrie picks most of them... but the flight is just too tempting, so she leaves without finishing the job properly. During her flight she sees that the whole castle is covered in lockweeds - and she has to find the key.
