"Letka/jenkka - SiIvaGunner: King for Another Day" is a high quality rip of "Letka/jenkka" from SilvaGunner: King for Another Day. It represents the King for Another Day Tournament contender Quote.
This is an arrangement of "Jenka 1" from Cave Story. Samples from the "Hey!" sample from "Artificial Intelligence Kong" by nelward, the "Come on!" voice line from Sonic the Hedgehog 3 & Knuckles, and the "Wow!" and Giygas Static samples from EarthBound are heard throughout the arrangement.
The title of the rip is a play on the Finnish dance "Letkajenkka". This could be because this rip was uploaded after Finland's Independence Day.
Note that Dual Arrangements are sorted by the placement of their rip in the offical playlist, under the character on the left of their thumbnail. This excludes Cool Meme Team, whose duals are both contained under them.
