We have a "Family Mascot" named Senor Chester Fluffypants. He's a basic brown Build-a-Bear with 4 hearts in him (double time lord? No, just one for each family member). We get him a little outfit for our big vacations and take pictures with him places (I don't like putting too many pics of my kids on line, so he is our stand in).
We planned on SCFp staying in the car, but DD wanted to take him in on Day 1. She was scared of the characters. OK, we said, figuring he would end up riding in the stroller all day. Well, she did end up taking him to each character, to keep her from being scared. And they *loved* him!
Merida, of course, had a big serious conversation with the girls about their bear (was it really their brother?) and made a point to present SCFp and the girls to her brothers in the barrels.
Winnie the Pooh and Tigger in England tried to "steal" the bear, and we had a fun 10 minutes or so playing with them in Christopher Robbin's bedroom.
Tiana called the girls back over after pictures as SCFp was in the stroller (last day, not so scared) to be introduced. The girls still laugh about how Tiana and Naveen cracked jokes "Fluffypants? But he's not wearin' any pants!"
Rafiki took the bear and performed the Pride Rock/Baby Simba blessing on him, overhead thrust and all.
Donald Duck pitched a bit of a snit fit... because SCFp was wearing a Mickey shirt. Mickey and Minnie signed his shirt, and took a picture with just the three of them.
And on and on and on.... I couldn't have anticipated this would be such a hit, but my DD loved having SCFp just for "security" to start with, but we ALL loved how much interaction he spurred with all of the characters.
