There are five different versions of Tixx's Infinarium, each one rewarding you with 100 Mystical Cogs when completed. Finishing all five grants you another 200, for a total of 700 cogs.
Each holiday mini pet requires 250 cogs to craft. This means that you can only craft two.
What are the remaining 200 cogs good for?
