OGBP

The OGBP is an item in Subway Simulator. 
You originally got it from the Contempvoid event in Subway Simulator.
In the Contempvoid, you had to complete three obby's to get the OGBP. Firstly, you need to complete three obstacles that weren't that bad. Secondly, you need to find a hidden door if you completed all of the three obstacles. Once you have found it. You can enter the second obby. In the second obby, you need to climb a tower of anxiety. After you climb to the top of the tower you need to find an invisible ladder to continue. Lastly, after you had to beat crypt again. (keep in mind if you died, you had to start ALL OVER.) After you have beaten the crypt once more you get the OGBP if you touched it of course.
This item was made originally for the game "Wander" later then removed and added in the Contempvoid Event due to somebody solving the puzzles and showing them to the Subway Simulator Community.
In the game Wander there were four colors for the rooms Orange Green Blue and then Pink
First, you start in Orange. Then Green. Then Blue. And then in Pink. Green starts the music from The Beginners Guide - Vault. When you made it to the last part of Pink you hear a ding and see an image that seems to be the color green and a spot of red. It turns out you need to find a secret door in the green rooms. The next puzzle was in Orange showing off a giant spot. Meaning it could be in the giant Orange room. It will show you another puzzle containing the Pink rooms. It looked like it would be in the last room of Pink. After you figure it out you climb a long staircase and walk in a very long hallway. You will hear the outside of the city. It turns out you left an apartment for some reason. Once you make it to the gate you win!
It makes a ding sound effect and that's it.
O-G-B-P = Orange Green Blue Pink.
