In this scene from 'The Muppet Babies', a group of young versions of classic Sesame Street characters - including Elmo as Blogg and Cookie Monster as Gonnigan - are learning about instruments in Mrs. Piggy's school class. However, things quickly take an unexpected turn when the toys come to life.

Blogg grabs his drumstick but instead of playing music, he starts banging on a real drum that appears out of nowhere! The students gaspared and ran for cover as Blogg continued beating away at the noisy instrument with reckless abandon.

Meanwhile across town in another part of school yard ,Gonnigan was having trouble keeping her maracas steady .They kept shaking so hard they almost flew right off her hands ! 'Help me somebody!' she cried out desperately.' Somebody please make this stop!!'

Just then,a giant boombox suddenly crashed through the window and started blaring music at ear-shattering volume. The kids covered their ears as Abby's trombone soared through the air towards them before landing with a bang.

'Okay okay everyone settle down now,' said Mrs Piggy sternly.'We're not going to play instruments today we're going to learn about them first!' She looked around expectantly at her students but they just stared back blank faced like sheep waiting for their next command. 'Anyone want to start?' she asked again, trying valiantly to get some sort of response out of these uncooperative little munchkins...
