My daughter's house has a Nemo and Friends bathroom for my granddaughter who is 6. Nemo, Crush, Seagulls, Dory and all the rest plus undersea sponges, corals and bubbles are on decals covering the walls. She has orange and blue towels, a multi fish toothbrush holder, soap dish, light switch plates and tissue box holder. And of course a Nemo and Friends large bathtowel on the towel rack.
Then her bedroom used to be princess decor but last year got changed to Tinkerbell and Friends. She has canopy bed with large (artificial) flowers on the canopy, curtains and wall decals of Tink, Irridessa, Rosetta, Fawn and Silver Mist, Tinkerbell clock/radio, Tink nightstand light, bedspread, sheets and pillows with Tink, a pink Disney TV, DVD player and jewelry box, a behind the door mirror decorated with Tink items - flowers, sewing things, trinkets and ribbons.
