How is the bonus round played after filling the jelly jar to the required amounts. I do not understand what the goal is. What do i do with the presents on the assembly line...and is there a purpose for the boosts that appear in the bonus round. I am just really confused. Also levels 623 & 625 will not show more than one star even though I have redone them several times ...the score reflects the correct amount and I forget and replay them and it's still stuck at 1.
