There are three antenna rooms throughout the game. The antennas are blue glowing objects that will make Trico go crazy. He will then try to attack and eat you. Being eaten by him is required to progress in the story and results in a cutscene. However, you must evade him for three minutes without being eaten to get the "Keep On Running" trophy. Just keep running around him in large circles for three minutes. You can do this at any antenna. If you do get eaten before reaching the three minutes, quickly pause the game and restart the checkpoint.
