Head up the stairs and if you get all the way to the top a crow will push a button and the stairs will fold causing you to slide down a bit, so put on your invisibility to get up by the crow. You can punch the crow when you get to the top along with getting the Psi-Card and brain that are hanging out right here.
Go up the ladder for another scene. If you watched closely you may have noticed whose brains he's keeping close by on his desk...either way to your right now is a Psi-Card. Now leave this area and go all the way around the path surrounding it to get 2 Psi-Cards and 2 Brains. There is also a doorway at the top you can enter in for another scene with this crazy girl, there's some old friends up here as well if you walk in further after the scene.
Grab the Birthday Cake on the table then head back into Loboto's area, but don't go into the purple section or else you'll get "caught" and be sent back up by Milla and Sasha. Stand on the side of the turtle tank by where you come in and take out the Cake, Polkeyope will walk over towards you then you can use telekinesis to toss him out of the cage. Pick him up and go back up to the girl for another scene.
After the scene go back down to Loboto, use your telekinesis to toss the brain into the tank and even more scenes now! Shoot a Psi-Blast at Lili to free her...
Scenes...
As of this point of the game you will not be able to go back to anything. Let me repeat. You. Can't. Go. Back. After. This. Point. For. Anything. However, the game will autosave for you right before this so if you want to beat it now then worry about extra things some other day, feel free cause you'll have a save waiting for you right here. Otherwise go back now and get whatever you want, then continue on.
First thing we notice is a lot of things get piled around the tank like a shield. There are some wooden planks right up tight to the tank and some blocks around that. In the environment are some rocks along with some green little rivers.
The rocks that are stationary you can throw, you can't throw the ones circling around the tank, and the green rivers will hurt you if you step in them. Now, here's what we want to do. Take the small rocks and use your telekinesis to toss them at the bigger rocks, each one you hit will break. However, there are hands that are bringing in more blocks and they will also occasionally toss one at you, you can tell it's coming cause it will get little crooked lines all around it like it's charging up or something, just use your shield to block this.
After you have several of the rotating blocks taken out you can use Pyrokinesis to light one of the planks on fire revealing the tank, then throw a rock at it to crack the shield a bit. After doing so the barrier will be rebuilt. Everything will then speed up, repeat 2 times.
After the third hit run up towards the tank. After the scene you'll be in control of your brain, there's not much to do but toss yourself via telekinesis into the tank.
