Time Out says
Relive every 90s game show fantasy you ever had at The Beast, the world's largest inflatable obstacle course at Alexandra Palace. Jump, bash and clamber your way through 32 inflatable obstacles across a 272 bouncy metres.
This is no ordinary blow-up castle. Street food vendors Saucy Chip and Taco Revolution will on site to help you tackle The Beast, alongside bars with cocktails, craft beer and prosecco on tap. There will also be a DJ set and light displays to keep you hopping along.
