It's just us, but big sis wants him to have a pinata

so, we've got a free Spongebob pinata that we'll fill. There probably won't be a theme besides that, as I'm not real keen on Spongebob, especially at these ages.
As for gifts, we are now insistent that the presents aren't full of little things that can get spewn all over the house, so I'm looking at a truck with buttons, sirens and flashing lights, or a toy workbench. He likes buttons, noise and flashing lights, so that's what we're aiming for.
