Cuckoo…

Three cartoon characters stand together in a snowy, stone-walled environment. The character in the center, wearing a tall green hat and glasses, gestures with his right hand while speaking, then turns his head to the left as the character on the right, wearing a yellow coat and orange hat, looks on with a concerned expression. The character on the left, in a red coat and green hat, remains still with a worried look. A fourth character in a green coat suddenly appears from the right, jumping over the character in the yellow coat, causing the character in the center to react with surprise.
