Aphrodisiac

Eccentric Professor Leviticus Wirtsus is obsessed with crossbreeding animals of different species. His research leads Wirtsus to discover a LSD-type substance called Fongaluli. The leaves of this substance cause Wirtsus' beloved lobster Shirly to transform into a beautiful human female. However, unless Shirly has a steady supply of Fongaluli leaves she will revert back to being a lobster. Wirtsus goes to a remote tropical island to find more Fongaluli leaves. During his travels Wirtsus encounters a libidinous female giant, a merry family of incest practicing freaks, a helpful sailor, and a fearsome jungle witch.
