Dr. Steinschneider first contacts the presidente by a letter, warning of a new biologically engineered virus. Despite his claims of not being mad, the presidente disregards the letter. When the warning turns out to be true and Tropicans begin hiccuping uncontrollably in The Hiccups, Dr. Steinschneider arrives to help, asking for 6 professors to act as his personal assistants. After some time, he concludes scaring infectees cures them. Since scaring infectees individually would be too time-consuming, he suggests building a movie theater to force patients to view horror movies. When this fails to end the disease, he suggests more scary entertainment, such as riding a rollercoaster or allowing bungee jumping off the Cosmic Pin. One of his Tropican assistants theorizes that drinking rum will cure the disease by replacing the 'infected' hiccups with normal, 'healthy' ones. To test the theory, he suggests building a rum distillery. Unfortunately around this time, he discovers that the disease is evolving to infect entire buildings, slowly making everyone that lives or works in them ill. The only cure he finds at the time is destroying the buildings outright. What's worse, his assistant's theory fails disastrously, with infected Tropicans still sick and now very hung over. Thankfully, he finally makes some progress. He finds a true cure to the disease while reading an old book on the occult; stand on one's head, drink water, and recite the national anthem. To dispense the cure, he asks that a new sanatorium and two water treatment plants be built and that a National Day be issued. He'll also discover that microwave radiation has shown some promise in disinfecting diseased buildings and suggests that building each radar dish built will disinfect one nearby building. After the mission, he'll confirm the reports that the virus is man-made and says that he believes that Tropico was simply a proving ground. However, the presidente suspects that the island was chosen specifically.
When Penultimo's strange behavior and unusual physiology worries Miss Pineapple in The Truth is Out There, she has a radio station built to contact Dr. Steinschneider, who concludes that Penultimo has been kidnapped and replaced with a clone. To find the real Penultimo, he requires gold to build a "whole-conductor" for his Gene Tracking Device. He's later called back to the island when a new virus breaks out across the island, causing people to transform into clones of Penultimo, along with his characteristic incompetence. To develop a cure, he asks for lots of chemicals. Unfortunately, the cure he develops is immediately stolen in what he suspects is an inside job. With help from the island's secret agents, he discovers that the Penultimo that was rescued is actually another clone. This clone is captured and the cure is administered to the island's water supply.
