First source which confirmed the development reads;
“He was convinced by his friends to get on the best ride of the park, Ferrari Land. The man, who knew he was suffering from gastroenteritis, accepted, and his nightmare started.
On the first slope, at a speed of almost 200km/h (124 mi/h), the man noticed that his stomach was not doing well. At the first looping, he couldn’t stop himself and was forced to let it all out. The shit was flying all over the place and splashed 14 people, who were sharing the exciting ride. Many of them threw up because they had shit on their hair, face and clothing.”
However, other reports denied the claim as the name of the park does exist .
