Harry Potter and the Chamber of Secrets (PC)/Whomping Willow & The Aftermatch

Advance to your right and avoid being slammed by the Whomping Willow's branches. When you see an opening to your left (brick wall), go into it. This corridor has tutorials for Alohomora, Lumos, Small Ledges and Save Books. The Dragon Fountain is bewitched, cast a spell at it. By now, you should have some beans.
