Hi

Blockzilla is a plastic foam toy made by the Goruko Toy Company Ltd. in japan in 1986 and exported to the city of Prypiat, Ukraine, where it was bought by the Bogdan family as a gift for their youngest son Olexander, who named him Fred. When in april that year the Chernobyl plant disaster occured, the Bogdans abandoned the city, leaving him behind. Exposed to the radiation in the area for a long period of time he mutated and thus became a kaiju.
