Spider-Man - Season 2

DESCRIPTION

A giant plant escapes from storage in a house belonging to Prof. Smithers, a missing scientist. Spidey goes through a portal (located in the scientist's home) to prehistoric times to find some defense against the plant and meets Smithers, who tells to him that two radium gems in an idol in a nearby city, if ingested by the plant in New York, will disintegrate it.
