Carl's House and Russell From Up
Hold on tightly!
What you need to do: For Carl's house, find a cardboard box and paint the house on the front. Attach balloons to the box or around your waist inside the box. For Russell, wear a yellow polo shirt and dye a white baseball cap yellow (use felt for the logo). Find either a vintage Boy Scout sash online, or make your own using bottle caps and iron-ons.
