F.L.A.R.G. is a holiday that is celebrated by the Yugopotamians or else their appendix will explode, which is powerful enough to take out a whole city. However, the holiday is never celebrated on their home planet because on the fifth day of F.L.A.R.G., the Yugopotamians say goodbye and blow up the planet that they celebrate it on. F.L.A.R.G. stands for a series of events that are repulsive and unappealing to humans, but very stimulating to Yugopotamians. In addition to the events, the Yugopotamians also toast manure, drinking the contents happily.
