A customer wants a dolphin cake- she brought me a dolphin pan, wants dolphin cake on top of a 10 x 15 layered cake. Wants dolphin to look like it's coming out of the water. Any suggestions???

Is the Dolphin pan 3-d?
Reguardless can you set it on the tail? dowel the tail and middle section and cover the dowel with a "wave" of fondant or make the wave out of royal icing.
hopes this helps, in my mind it works...
