Hold on to the owl
From the Super Mario Wiki
As the name implies, this level is another one featuring the sleepy owls. However, the owl is not available from the start. The player has to go up on foot and find a Switch Block before the owl can be accessed. The player can then traverse the maze safely, though he or she still has to watch out for the spiky traps that form the maze.
Hidden Treasure: Tome
The hidden treasure of this level, the Tome, is located directly in the first area of the level. The player will need the owl to reach it. From the point at the beginning where the owl can be found, they should head left and avoid the Kotsuheri. They then have to have Wario fly up and then left again. On the far left, behind various coin flocks, the treasure door can be found.
