This tent is made by Twinkle Play Tents ($40) or so. Jonah got it for Christmas from Grammy and Papa and he absolutely LOVES it. We put a bluetooth speaker in it and turned it into a dance party. It is motion and sound activated (or so my wife tells me).

Sensory play for days.

Edit: Facebook muted the sound because of copywritten songs in the background
