When you get the present from the snow bear, take it to Blue's Beach Hut and give it to him. When he opens it, he will give you it. Immediately before the bowling ball gets into your item box, run out of the cabin. If done correctly you should not have gotten the bowling ball. Do not save or else you will not be able to get the bowling ball back. You need the bowling ball to get a Banana Bird. If you go back into the beach hut, Blue will not have the ball and neither will you.
