Psychonauts

Story Related, cannot be missed.

After clearing Waterloo, you can go upstairs in the Asylum to a room where you’ll find an artist named Edgar, who is troubled by something that happened in the past that prevents him from making portraits. Delve into his mind to solve the issue and start Black Velvetopia. You must find four cards scattered throughout the town to finish Edgar’s deck of cards so that he can reach his girlfriend trapped in the sky (keep the missable helmet required for I'm Gonna Live Forever in mind before doing this). To obtain the cards, you must defeat the luchadore wrestlers who reside within the cards in a battle. Their attack patterns are shared across the four fights so defeating them isn't too difficult (once you've beaten all 4, refer to Look at those Pansies!). After finding all four cards you will be put in a two phase boss fight against the bull that terrorized the town earlier in the level. Defeat the boss to earn this trophy.

Boss Tips: In the first phase you will fight the bull "El Odio", his attack pattern is pretty basic. The bull will charge you a lot, avoid the attack by using Shield and when the bull crashes in the wall use Telekinesis on the objects in the ground to throw at El Odio to damage him. Rinse and repeat until the second phase, where DIngo joins in. Firstly remove all of the pokers you put into El Odio, because of he is defeated you will be defeated. Secondly use confusion grenades on Dingo to stun him, then attack him while he is stunned to damage him. After you have done this enough times he will be defeated.
