To get rid of the squidbunny you need to insert the C-ALPHA into the cleansing equipment (second romm to the left when spawned in the labs)
To get the first recipe you need to use the Mainframe and read its log (where you can turn on the lights) or from the site Zeta one (entered from the looped forest if you are infected)
The second recipe is in the labs PC in one of the small room
Then you need to get the vials one is in the lvl 3 card room the other down from the squidrabbit
you can cross the flesh tentacles while infected
The Site Zeta entry is a tricky one for first timers if guide needed i can give it to you
