the fourth design that really took off to steal The Great Prism, but after fighting off the Joyces/Verigreens, it was sliced down the middle when it got a hold of The Great Prism. It made other appearances in two episodes, 'A Spectre Kalls,' and 'No Presents for Khristmas.' "Kalkulator" (Sparky) A supercomputer used in the episode of the same name. Built by Synapse the computer mechanized Krud city, all inhabitants received a door operating PIN, Verigreen detectors and automated defenses were placed. Draffsack himself had problems with the design, seeing as he chose the PIN 1,999,999,999. However, the main feature of the computer was its Auto-mated Lumberjacks. To stop the latter Flynn sneaked into the city in a Hold of one of the lumberjacks and evaded capture as only Synapse knew a B12 alert meant a Verigreen was in the city. (Greeb: Good thing you know it, I don't have to look it up in a codebook. Drum-sturdy: There's a codebook?). The system was corrupted by a colored data card which had been hit by Flynn's color gun. After Krud city went mad Draffsack ordered the scrapping of Sparky. "Auto-mated lumberjacks" Minions of Sparky, these machines were virtually indestructible to Verigreen technology and able to decimate the flower forest. A unique feature was a color detector which enabled them to home in and attack Verigreen technology. This was exploited by the Verigreens who used color sprays to lure the machines over a cliff. However, during the night they righted themselves and resurfaced out of the water. They were ultimately defeated with the downfall of Sparky despite their incredible success. As of the events in 'No Presents for Khristmas' they were still seen working on a small scale during Krud raids, mainly to stop Verigreens hiding in their holds. Koal Juice Guns The Yuk counterpart to the Kolour Guitar. Being hit by koal juice causes depression in Joyces, which may be cured by the energies of the prism. Most Yuk soldiers and most vehicles are armed with the weapons. Yuks appeared immune to Koal juice, but it still becomes stuck to them, as it does with Joyces. Koal juice itself is a dull green substance. Vokalizers A walkie-talkie-like microphone that the Yuks/Kruds used after their voices were affected. It only appeared in a two-parter "It's Katching/Epidemik" and "The Kure". A similar Vokalizer was seen in "Fulgor's Kwest/Krud Konfession", possibly as a
