Better image of Doodle Patrick. Evidently he grows after you attack him according to what I was watching.
This is indeed Doodle Patrick. Sorry about the blurriness but this is the only image I could find.
Doodle Patrick is an main antagonist of Drawn to Life: Spongebob Edition. His first and last appeance is in Dutchman's Ship. He appeared as a crudelydrawn Patrick who is smarter. He first appeared lying to the Flying Dutchman, making him blame Spongebob and Doodlepants. But later, Spongebob and Doodlepants convinced the Flying Dutchman that Doodle Patrick is the liar. He then appears as the boss of the Deep Sea.
He has a very easy strategy. He rolls around the screen and occasionally jumps off the screen and falls down causing a shockwave to roll across the ground on both sides. He also runs around the room. It is very hard to hit him. The only second to hit him is when he is not doing anything.
