The bird looks at you for a second and then starts eating the marshmallow!
After the last marshmallow was eaten, the bird sat on the grass and started singing a Justin Bieber's song!
Do you:
Sit down on the grass next to the bird, and sing along?
Use the leftover marsmallow as earplugs and run away?
Realize that the bird is a great singer and decide to take it to American Idol
