The Dense Detective. What are the Wolves Guilty Of?!

One evening in the Dense Forest, a terrible roar was heard. At the sudden clap of thunder, the roof of the witch Charlotte's cottage jumped, the cat Ludwig fell under the table, and a barrel of honey toppled onto the... head of a bear dozing in the den. The worried animals, together with the young fairy, set off into the thicket of the forest to find the culprit of the uproar. Could it really be the gray wolves' doing?
 
In the Dense Forest, the fir trees are shaking!
The residents are in a panic: — What kind of calamity is this?
Something wicked is afoot with the wolves.
Oh, how we hope not to get in trouble with them!
