At the credits ending of Cloverfield, *spoilers* the audio from the video cam says, “Help us!”. But when played backwards, it says, “It’s still alive!” This happens after the end credits of Cloverfield. Assuming the speaker was Rob, he suggests Cloverfield (the monster) is still alive. This also suggests a sequel for Cloverfield 2! *Spoilers*

The Japanese oil company TAGRUATO drops a satellite (Chimpanz III) into the ocean as part of viral marketing (shown at the end of the movie when Rob and Beth were on the ferris wheel). TAGRUATO works with SLUSHO (a slush company), as the main ingredient for SLUSHO is found at the satellite dropzone (deep ocean). While searching for satellite and ingredients, they woke Cloverfield (the monster).

People who were at the party in the beginning of the movie, were seen wearing SLUSHO shirts. Rob apparently was going to be the Vice President of TAGRUATO in Japan.

The main ingredient of Slusho apparently turns a tiny fish into a HUGE whale in Ganu’s (he found the nectar) dream, which explains the size of Cloverfield. *Update* The main ingredient is a deep sea nectar.

*Update* Because the ingredient was discovered on the deep ocean floor, under amazing pressure and in the most extreme cold, Ganu knew he had to serve the ingredient in a near frozen state to preserve its freshness. Thus the idea of Slush (Slusho)!

For animals/fishes/insects to survive in the deepest ocean (very high boiling temperature), they naturally have very high heat resistance. This explains how Cloverfield is able to withstand numerous bombs and attacks from the army.

Cloverfield refers to the field formerly known as Central Park. Clovers are usually prone to grow at places after bombing. Thus the term “Clover” and “field” referring to park.

*Update* Slusho is a very addictive drink, with signs of steroid drug like effects. Makes people stronger, constantly happy, have happy dreams and finally… “SLUSHO makes my stomach explode with happy!!” (Remember Marlena’s stomach?)
