This was the first party to not be an expedition in January, since 2009.
Gary's removed mascot scripts indicate that it was originally supposed to take place in the past and future, at the time it was called the Future Fest.
Judging by Gary's mascot script, penguins traveled to the Senonian epoch of the Late Cretaceous, around 72.1 million years ago. Despite this, both Tyrannosaurus and Triceratops are from the much later Maastrichtian epoch of the Late Cretaceous, about 66 million years ago.
It plays different music than expected when you log in on certain occasions.
If you wear a clothing item such as a Propeller cap, a Unicycle, etc., (Special Dances) then dance (hit D on your keyboard), and transform into a Dinosaur, you will see your penguin as you are a Dinosaur. You then have to move around. Then hit transform back.
Sometimes when you travel to the present and right back to the prehistoric time, you will seem to have a bunch of coins, but if you try to buy something, it will say you don't have enough coins, then show a never-ending loading screen, which makes you have to log off and back on to fix it.
Similar to the Halloween Party 2012, you can dance while transforming into a Dinosaur, but you will be a dinosaur also, you use an item with a special dance and then you transform into a dinosaur, which you can do the action even though you already transformed into a dinosaur, but you will be a Dinosaur also.
Sometimes when you log in at the prehistoric time, the spy phone will be above the map.
In January 19, when you tried to claim the Waterfall (furniture) it would say it was unavailable even though it should have been available. This glitch was fixed the next day.
If you clicked your Player Card as a Pteranodon and then clicked a place on the wall while you transformed back into a penguin on ground, your penguin would waddle onto the wall.
If you put on the tour guide hat and hold up the sign, then become a dinosaur, the dinosaur will be holding the penguin and you can carry it anywhere like it is your prey.
Sometimes when using another browser the eggs you collected in the previous browser will be gone.
If you go to 2013, and open your EPF Phone then open your Map to go back to dinosaur times, your Spy Phone would be above the map.
