A narwhal sitting on a stool is your friend.
Imagine that narwhal sitting there. It waves its flipper and says "hi friend" to you.

"Hi friend," says the narwhal. "I must warn you about all the youths." (ゆう)
Your narwhal friend goes on to warn you about all those youths, and how they will try to take away your friendship with their good looks and young ages.
