What this means is he will be replacing Marie (from The Artistocats) at the flagpole location. Stitch and Pluto will be meeting simultaneously with separate lines from park opening to about 2:30pm.
As of right now, it looks like Marie will become the newest character casualty. Before her time at Magic Kingdom, she met in EPCOT’s France Pavilion. I see it unlikely she will return to EPCOT in lieu of all of their entertainment alterations.
Now, the rumor is he will be pulled from the “Move It, Shake It, Dance It, Play It! Street Party.” If not, that will involve quite a bit of running around for the little blue alien.
Expect these developments to take place on May 10th. Remember Disney’s policy: “Everything is subject to change.” So stay tuned.
