Darren Criss and his Warblers better watch their backs! With 'Glee' on hiatus for the summer this little boy is filling the void with his spot-on impressions of the Dalton Academy singing group that captured hearts this season. The tiny Warbler has it all down -- the singing, the moves and and even the costume! He's just a little too young to be anyone's Teenage Dream yet.

The 'Glee' cast, complete with members of the Warblers, is on tour this summer performing hits from the series. Check out the mini Warbler's moves and tell us what you think!
