Sloobagloobs

The Sloobagloobs (also known as Chrono-Dumpers) are creatures which are first mentioned in The Dookie Loop Horror.

According to Zim, the Sloobagloobs are interdimensional creatures that actually eat time in the dimension they're from and use our dimension as a toilet.

The time poop is responsible for the loop.

Zim boasts about somehow tricking one (or several) of these inter dimensional aliens to use an interdimensional toilet in our dimension and then collected their guano (which Zim and Dib refer to as "time poop"). This substance is explained to be highly unstable, but Zim somehow managed to harness the energy within a containment device, which he intended to use to turn humans into babies and send them towards the sun in an attempt to finally conquer the Earth.

However, GIR gets inside the container with a pig which farts, breaking the container, which causes a "time-poop rupture" that wipes out the entire universe but also results in an never ending time-loop where everyone is forced to relive the same day over and over again, with only Zim and Dib aware of the loop (Zim thanks to a special hat he designed and Dib thanks to a device Gaz shoved into his head).

Facts of Doom[]

The Sloobagloobs seem to be floating heads, as they don't appear to have bodies.
- Their heads also seem to resemble inside out plungers, with craters and lacking noticeable mouth and eyes.
- However, they do seem to resemble Gaz when her eyes angrily close, suggesting these creatures either don't need much light in their home dimension or they're perpetually angry.
The fact that they're also known as Chrono-Dumpers seems to suggest that it's a nickname given to them by other species.
How they're capable of eating time its never explained.
Their poop is blue and highly unstable, suggesting that the species itself may be dangerous.
The fact that one of them was tricked by Zim hints at the possibility that they may not be too smart.
