No, Royal Icing is the kind that goes hard when dried. it has eggwhites in it. It's the kind used for the little flowers you can buy for cupcakes etc.
What you want is a soft icing.
Here's one recipe: Soft icing - Better Homes and Gardens
I actually have a packet of the Woolworths Ready Made Icing left (My DD turned 1 a couple of weeks ago). If you want, I can send it to you. I don't even want money. It's just taking up cupboard space anyway. Just PM me your address.
Oh, and I promise, I'm no creep, I won't stalk you or anything
