Disclosed embodiments may include a trampoline scooter device for practicing scooter tricks on a trampoline. The device may include a foam deck with an upper surface and lower surface, where the upper and lower surfaces both contain a first recess. The first recesses are designed to receive, respectively, an upper attachment member and a lower attachment member. The upper and lower attachment members and the recesses contain aligned holes to receive connectors. The upper attachment member is connected to the headtube of the scooter via the neck. The headtube contains connections to the column, which is attached to handlebars containing grips and grip ends. The foam deck may include one or more deck weights at the end of the foam deck opposite the attachment members, either embedded within the deck, or within a second recess of the upper and lower surfaces. The foam deck may include a spine support.

An apparatus for receiving one or more activity attachments including a deck having one or more openings along a long axis of the deck and between the top surface and the bottom surface of the deck. Each of the one or more openings having a circular aperture for receiving an accessory of a set of accessories. Each accessory of the set of accessories providing an activity for a user of the activity. Each accessory having an attachment platform configured to attach the accessory to the board. The attachment platform having a locking mechanism to engaging with a complementary locking mechanism of the board.

A bouncy castle grounding assembly for discharging static electricity from a bounce house includes a bounce house which has an inflation tube for inflating the bounce house. A fan is fluidly attachable to the inflation tube to blow air into the bounce house for inflating the bounce house. A grounding band is positionable around the inflation tube and the grounding band is comprised of an electrically conductive material. In this way the grounding band to be in electrical communication with the bounce house. A ground wire is attachable to the grounding band such that the ground wire is in electrical communication with the inflation tube when the grounding band is positioned around the inflation tube. The ground wire is attachable to a ground to discharge static electricity from the bounce house.
