S12·E9 The Party Surprise

Freddie decides to organize a winter party at the wharf instead of at Mr. Percival's house, so that Colin the Crane can join in, but neglects to tell Mr. Percival and so the equipment is loaded onto a barge. Freddie eventually tells Mr. Percival about the rearranged party, to which Mr. Percival agrees on. Freddie stops the barge just in time and the party is now on the Wharf. Colin thanks Freddie for his help.
