First Planet Puzzle!

Buggie has been learning about planet at her preschool and shes been teaching me the solar system song: Mercury, Venus, Earth and Mars, Jupiter, Saturn, Uranus and Neptune, in the solar system I created this APP since 2-3 years-old kids have strong interests in putting together puzzles and I want to help them to remember the basic facts about the planets while playing. Now if I ask Buggie what is her favorite planet, she would tell me its Jupiter, because its the largest in the solar system.
