Professor Poopsnagle's Steam Zeppelin S01 E06 Island Adventure (II)

Once they had landed on the tropical island, they found themselves confronted by a weird sound, and they also discovered footprints of an enormous size which indicated that there was a monster on the island. The cryptogram of the last salamander, when it was deciphered, turned out to be the island that they were on. Inadvertently the storm had placed them on the correct island, so they decided to split up in various groups to search for the next salamander and the next mineral.
