From the Disney Parks blog:
For all you Disney Channel fans, Phineas and Ferb made their Disney Parks Christmas Day Parade debut during a taping at Disneyland park this week. The characters do not currently have an ongoing presence in the Parks, but the Disney Parks Christmas Parade taping is the first time they have appeared anywhere. What do you think of these new characters?
I think they are so cute. I really hope they begin doing MnG’s in both park in 2010. My kids would love to meet them, we really like Phineas and Ferb around here. We are also really looking forward to the parade on Christmas Day.
