The first short is entitled Toy Story Hawaiian Vacation and you can read the plot details below.
"Bonnie is off to Hawaii, and Barbie and Ken are excited to go along on their first tropical vacation! But when they're accidentally left behind, it's up to Buzz, Woody, and the rest of the toys to create a Hawaiian paradise right in Bonnie's room."
The story line came from a description of an upcoming children's book Play-cation!, which will be published by Random House on August 9. The book is said to be based off the animated short.
No details were given on the second short, which will debut before The Muppets. We reported back in November that Toy Story 3 will be the final feature-length movie in the franchise, although these new shorts will allow fans to see their favorite Toy Story characters again.
