Finn and the Floodgate's Grin

While riding his bicycle along a polder path, Finn discovers carved wooden pieces hidden inside an old willow tree. Realizing they are the missing "teeth" of the nearby sluice gate, he solves the puzzle and fixes the gate just in time to hold back a rising sea tide. Oom Willem later arrives and approves of Finn's independent work.
