Zim plotting something evil with birds

Could the deformed bird be part of ZIM's evil plan?

During a meeting of the the Swollen Eyeball Network, Dib reveals his latest discovery, a bird which appears to be a normal grackle which has been rendered round and given a third leg.

Dib states his belief that Zim is responsible for its creation, but when he visits Zim's base, Zim flatly denies this, stating that while he does have a plan involving birds, it's not scheduled until the following week.

Despondent that his only lead has turned up nothing, Dib decides to dissect the grackle, causing it to panic and flee into the woods. Dib follows it, and discovers a radioactive green goop.

While he's scanning it to determine what it is, he's attacked by a raccoon, which eats some of the goop and mutates, gaining a second tail and a third eye. Dib is excited to learn that the goop is responsible for the mutations, only to panic as the rabid raccoon attacks him. Despite this, he's still excited at the situation, even as he gets his head stuck in a tree branch while fleeing the raccoon.

Dib finds more strange birds

Another mutated animal, a buck with a second butt growing out of its original butt, then shows up and attacks the raccoon. To Dib's surprise, the raccoon wins, and then flies away (using its tails as a propeller) with the buck in its mouth. Dib watches it go, then falls out of the tree and finds a trail of the goop, which he follows to an abandoned carnival.

Investigating the carnival, Dib finds many more mutated animals, including the grackle, which leads him into the main tent. Inside, Dib finds the source of the goop - a spilled container of old ice cream. He also encounters a heavily mutated "super bear", which attacks and begins chasing him. Dib tries to fight back, but his efforts all fail, and he finds himself lodged inside a cannon. Just before the bear can attack him again, however, the grackle ignites the cannon, launching Dib into the bear, knocking it out.

At this point, a group of people in hazmat suits arrive and begin rounding up all the mutated animals. Despite Dib's assumption that they're government agents, the man in charge reveals that they work for Fat Boy Ice Cream.

Zims plan comes to fruition or whatever the seed version of fruition is

ZIM's plan comes to fruition

The ice cream Dib found was their failed Green Apple Gamma flavor, which they couldn't sell because it kept contaminating other ice cream, so some district manager sold it to less picky clients like the carnival. Since then, the company has been tracking down the carnival in order to destroy all the ice cream, which could be used as evidence in a class action lawsuit against them.

After explaining all this, the team leader tells Dib that he has to be decontaminated, due to his close contact with the ice cream. This results in him being sprayed down with hot water and shaved bald.

The next day, as Dib's recovering at home, Zim shows up and announces that he's taken the opportunity to move up his big plan with birds - pouring bird seed over Dib's head and having a bunch of birds attack him.
