The Fresh Beat Band
From the Nick Jr. channel live action kids' series of the same name (2009-2013). If you gave The Monkees a lobotomy, a horse-pill-sized dose of political correctness, and an insatiable appetite for fruit smoothies, you might end up with something like this show.
At least the black one's not in a wheelchair.
Lineup: Twist (Jon Beavers), Kiki (Yvette Gonzalez-Nacer), Shout(Thomas Hobson), and Marina (Shayna Rose 2009-2011, Tara Perry 2011-2016)

The series was revamped in 2015 as Fresh Beat Band of Spies, an animated, not live action version. The same actors provided the voices, and yes, now they're spies, for a given definition of spies.
