Enter Sandy's dream bubble. Knowing how to do the Cruise Bubble torpedo is recommended. Switch to SpongeBob in Sandy's dream, then look to your right. There should be a long line of Tikis. Aim the Cruise bubble (L1) at a Storm Tiki furthest out. The screen should read "Super-Ultra-Mega-Monster-Combo". You should get about 275 shiny objects. Then, jump off the ledge and repeat this as long as desired. It is possible to get about 5,000 shiny objects in about a minute.
