Depending on the variant you play there are 3 senarios: 1. In the Basic game if you dropped it you get no points for the Barks with leaves on them at the end and it goes back on top. 2. In the Beginner game the Panda Cub isn't used. 3. In the Classic fun game the Panda Cub eats 1 of your Barks with leaves on them and then goes back on top of the Bamboo Shoot.
