The clouds hide ? Blocks, ledges, and other coins. Remember this as you ride the Jumbo Rays across the level.
Wait for the Jumbo Ray to pick up the P Switch on its back, then ride the Jumbo Ray with the P Switch to the right a little bit. Hit the P Switch to reveal several blue coins and grab them as you ride the Jumbo Ray deeper into the level.
At Point 4, drop down the hidden ledge to grab a POW Block. Slam it down for a shower of coins.
