It was nightime when Doodlebob tried to exact his revenge. After Spongebob erased him, him and Patrick went back to their homes not knowing that a part of Doodlebob was still alive, his right arm to be exact. A moment afterwards Spongebob managed to grab ahold of the Magic Pencil that Doodlebob had stolen earlier and then used it to erase Doodlebob from existence. But Doodlebob got the surprise on them however and then picked up Spongebob before Patrick said to him "Happy Birthday!" Patrick then gave Doodlebob the rock which Doodlebob then slammed on Patrick's head. Patrick thought that when Spongebob said surprise that he meant a party. Spongebob said that on the count of three that they'll surprise him. While Doodlebob was distracted Spongebob came up with plan that involved hitting Doodlebob with a rock with seaweed on it. Later on the two found Doodlebob in another clearing where Doodlebob was practicing swordplay or pencilplay as the case may be with no one.
One when the ball hit Patrick and the second when the ball fell down the hole and hit Patrick again. Doodlebob drew a bowling ball and used it on Patrick as if he were a bowling pin and even got two strikes. Next he drew a wrench and dropped it in the hole and on top of Patrick who then said "Where's the leak, ma'am?" They then tried to climb out of the hole which was less than successful. They proceeded to Doodlebob's pineapple where Doodlebob drew a hole in the front of his house for them to fall in. The duo later found Doodlebob in a clearing inside a "poorly drawn pineapple" as Patrick put it. But when Squidward answered the door and saw Doodlebob, he immedieately started to beat up Squidward and then took the magic pencil from Spongebob's grasp and ran off with it. It was supposed to go like this: Spongebob would knock on Squidward's door and when Squidward answered it, it wouldn't be Spongebob. After that Spongebob then drew Doodlebob as part of another prank. When Squidward tried to pick up the dollar bill, Spongebob yanked it away thus making Squidward fall and drop his hair which then flew away. The first one was the classic money gag in where you tie string to a dollar bill and be amazed at how greedy people are as they try to catch it. After Patrick's mustasche flew away, Spongebob decided to play a few pranks on Squidward. Patrick then decided that he wanted a mustasche so Spongebob drew him one and afterwards it flew away only to become hair for Squidward.
When this comes to life Patrick decides to erase it for good. Patrick then takes the pencil and decides to draw a caracature of Squidward. When it becomes alive is when they realise that they do not have an ordinary pencil in their grasp. Spongebob takes the pencil and draws a jellyfish. Spongebob touched it and realized that it is just a giant pencil.
When the pencil hits the ground, the two start running around scraming until they start to think that it may in fact be a giant pencil. While it was falling, Spongebob and Patrick were playing a game of rock, paper, scissors with their bubbles.
The beginning of the episode starts off showing an artist at sea working on something when he drops his pencil into the ocean.
This episode aired a long time ago and was when Doodlebob was both introduced as a character of the series and taken out of it too. Doodlebob hails from a single episode of Spongebob Squarepants called Frankendoodle and also from the Drawn to Life sequel, Drawn to Life: Spongebob Edition.
