Next time if you see a sign with multiple stars on it use your magic wand and turn it on. It wil activate special features like opening up the treasure chest. Those signs are spread out the whole park.
32:00 unless I am mistaken, that is the (artificial) fortress island of Pampus. It was built (on a preexisting sandbank also named Pampus) in 1887 to protect the Pampus fairway from attacks coming from the (then still open) 'Southern Sea', now lake IJsselmeer which has been closed off from the North Sea by the 'closure dike' (Afsluitdijk) since 1932. For centuries, ships couldn't pass the island (and before that the sandbank) at low tide and had to wait idle for hours for high tide to roll in to continue into Amsterdam. During that wait, the ships' crews had nothing else to do but drink and eat and wait. Hence the Dutch expression "voor Pampus liggen" (to lie before Pampus), which nowadays means something like 'to lie around exhausted, doing nothing'. You can only get to Pampus by boat.
