Sparky Mark II
From KeenWiki
A Sparky Mark II in Episode X
The Garg-replacement in Episode X is a reference to the Sparky in Keen 5, which behaves similar to the Garg, only that the Garg charges faster. This is why in Episode X Mortimer states about the Sparky Mark II: They are like the Shikadi Model, only improved. Faster.
