Nickelodeon brought its special brand of ’90s nostalgia to the BMO Harris Bradley Center Friday night, allowing fans to participate in games and activities inspired by their beloved ’90s shows like Double Dare and GUTS (complete with iconic green slime, of course). Fans had the opportunity to meet classic Nickelodeon characters like the Rugrats’ Chuckie, Tommy and Angelica, and the Temple Guard from Legends of the Hidden Temple while Kel Mitchell and Jeff Sutphen hosted the evening!
