 A few months after the ride opened in 2006, the yeti figure's framing split, threatening catastrophic malfunction if it were to be operated further in "A-mode".Since then it has been operated only in the alternative "B-mode", in which a strobe-light effect is used to give the appearance of movement, earning it the nickname "Disco Yeti" from some fans.It is speculated that the problem was caused by damage to the yeti's concrete base structure, which is unlikely to be repaired until a major refurbishment in the distant future, because the design limits access to the yeti without major disassembly of the superstructure.
