In "Regents Park", the six crates are easy to find. One is near the clapping monkey closest to the waterfall, another one is in the small tunnel under the waterfall. There are two jack-in-the-boxes where the one under the waterfall is found. The third one is on the large stones close to the hill with the two Cruella cars. There is one jack-in-the-box and two clapping monkeys. Watch out for Jasper. The final two are near the 102. One is in the gate which you open by defeating the Cruella car there. The last one is directly in front of the 102.
