Hop to the collectible you need:
Green Star 1
Near the start of the level is a portrait of Boo. Jump into it to be transported to a twisting room with a Green Star inside.
Green Star 2
In the library, start hopping on top of all the bookshelves to have them move in different directions. The bookshelves on the left hide the second Green Star.
Green Star 3
Just before the last door that leads to the flagpole is another love seat. Have it carry you to the floor above. Try to enter the green warp pipe to have it disappear and reveal a Green Star.
Stamp Location
Hop onto the love seat near the start of the level to have it float up to the Stamp above.
