Garalina was a video game company, best known for supposedly creating and publishing Petscop. Not much, if anything, is known about the company itself and its operations. There is no trace of the company ever existing other than Petscop. It can be presumed that Garalina was defunct by the late 1990s.
As of Petscop 12 no real-life info about Garalina has been discovered and it has not been discussed during the Petscop YouTube videos. The one instance in which it was mentioned at all was during the beginning of Petscop 1, where Paul quickly mentioned that the game was made by the company after watching the brief opening cinematic introducing it.Based on the lack of information and background, it is assumed by most that Garalina is a fictional corporation created to advance the Petscop story.
