Roll No. 21

Its raining bugs at school. There are bugs all around. In the shower, in Kanishk's coffee, in Suparna's make up kit etc. And none other that Vrishchika - the scorpion lady from netherworld is responsible for this. She's come seeking revenge from Kris. Meanwhile Dr. J gives the kids a an assignment to collect the highest number of bugs. The kids collect the bugs in jars.

Madhu the geek creates his virtual alter ego, called Maddy, on a networking website. Its way of becoming a popular kid in class. Maddy is everything that Madhu had always wanted to be but cannot. Maddy is not a geek, looks suave, he is funny, he is a hero. Maddy has become the talk of the school. Dr. J hatches a plan to use Maddy to defeat Kris.

A knock on the head, makes Kanishk lose his memory and he thinks that Kris in his best friend rather than his sworn enemy. He doesn't even remember that he's the school principal anymore. Kanishk begins acting like a kid and sticks to Kris like glue. Though it is fun at first, Kris soon becomes bored…no enemy, no Kanishk equals to zero fun.

Kris has been behaving strange at school. He paints a moustache on Pinky's doll's face. Kris helps Golu bullBablu much to the surprise of both of them... Madhu's specs are missing and Kris makes fun of him... Kris trips Sukhi as he is raking the leaves... Everyone hates the way Kris is behaving and can't figure out why? Actually , this is Tarak and Kanishk's evil plan.

Pinky wants to keep a pet puppy. But Kanishk would allow that at all, he hates animals and animals hate him !! Kris gets an idea to make his friends' wish come true and also an opportunity to stoke the fire of Kanishk's wrath at the same time. Kris puts up a sign outside the ashram, “Free Pet Wash” and within no time, the ashram is filled with pets from all around Mathura.

Its Bablu's birthday and the kids are preparing for a surprise birthday party. Kanishk has got a whiff of the surprise birthday plans and is plotting to make Bablu's birthday alsos Kris' last day on earth. To ruin the birthday plans and to get rid of Kris, Bun Bun mausi (demon spider) is called from the netherworld.
