The following are found on the DVDs, although some can be found without the DVDs. Other than Bloody GIR, these Easter eggs range from transparent images to even deleted scenes.
The Most Horrible X-Mas Ever
Alternate Jingly Bells scene
Switch to animatics for the alternate scene of "Jingly Bells".
Tak: The Hideous New Girl
Before Tak leaves, Zim has no contact lenses (same as in The Voting of the Doomed). His face is seen from the side and for a very brief moment of time.
Transparent image
Go frame-by-frame when Gretchen is crying, seen just after the transmission of Tak pops up. As the camera zooms away from Gretchen, there is a transparent transition of 2 views of Tak and Dib talking.
Alternate "Attempt" scene
In the scene where Zim begins his numerous attempts to learn human 'affection', if one switches to animatics, one can see an alternate version.
Video Clip
At the part where Tak is describing her downfall on Devastis, you see her in front of an Irken Control Brain for a short time. On the Control Brain's main screen, a few clips from the very beginning of The Nightmare Begins can be seen, namely the ships that fly towards Conventia as the title appears.
Unveiling Tak's Plan
When Zim, Dib, and Gaz view Tak's plan in Zim's base, Dib's shirt is white and his ears are missing.
Hobo 13
An alternate Hogulus canyon scene can be viewed when one switches to animatics.
The Wettening
A little movie clip that goes even when paused (go frame-by-frame).
Abducted
Escape
Alternate escape scene (switch to animatics).
JTHM
A copy of Jhonen Vasquez's Johnny the Homicidal Maniac is "fused" to the blob alien.
The Girl Who Cried Gnome
The paramedics in the back of the ambulance that take Moofy away are vampires (switch to animatics for a single frame).
The Voting of the Doomed
During the 'awkward silence' scene, Zim's contacts are missing. This could be because it was in Dib's mind.
