1) I think Monster High is a Nickelodeon show... But doesn't play very often. It is a fun show, I have caught it a few times while watching a friend's daughter. :)
2) The colorful duct tape is typically being used to make/decorate things... I have seen kids make prom outfits, jewelry, accessories, cover shoes, cover notebooks, decorate backpacks, etc.
3) I washed regular doll clothes, and they turned out fine.... But I think you would have a better bet using a big bowl. You could give your daughter a wood spoon, and have her agitate them. She might find it fun. Lol.
4) it doesn't hold up too well... I have found that leaving pancake batter slightly lumpy makes for fluffier pancakes... If the batter is left in the fridge then the lumps I leave would get too soggy, and my pancakes would tart tasting like my grandma's. (not a good thing! Lol.) I think mixing the dry ingredients ahead of time would cut down on time though.
