Dog in Room
Use Cody to beat the dog in the small room of the hotel. Jump over the dog and run to it to get its attention. Stand on the small ledge and jump backwards so the dog chases you. Use pies to kill the dog, but the dog must be shot with pies at the exact moment that the dog barks.
Mission 3 Boss Fight
Change your character to Cody to throw pies and balloons at the ghosts in the room. Avoid the ghost's attacks with the right and left arrows. Point at the platform for the best aim. When the ghost's energy is at it's lowest, hit it one more time with a pie or balloon. Switch to Zack when the ghost is trying to recover and open the window to make one of the ghost icons disappear with the moonlight. Use the red, green, blue and yellow colors to ultimately defeat the ghost.
Mission 4 Vacuum
Turn your character into Cody and use the red switch to stop the waterfall. Move the sailboat using the left and right arrows. Change to Zack and head right to the large rat; change back to Cody to defeat it. Refill the vacuum cleaner with the dispenser and use the vacuum to defeat the rat. Next, use the vacuum to suck the cart away from the wall to jump on the platform above.
Mission 4 Sailboat
A letter must be delivered to Mr. Moseby telling him thieves are in the hotel. Switch to Cody because only he can complete this. Use the left and right buttons to move the sailboat, but make sure you do it quickly because it is a timed mission. Blow in the microphone to make the boat move faster.
