Great Journey Toy location: Save the Spectre at level start, and when you return here after meeting up with the Scarab, drop down over the cliff in the Spectre. Drive the Spectre out to the beach on the right side when facing the large structure and out into the water. You should see a rock formation you can drive up onto that leads around behind the structure. Drive up onto this and follow it to the end where there is a very steep mountain. Simply climb this mountain using the Spectre and you will find your last toy plushy at the top. Check the collectibles video beginning at 21:06
