A Care Bears-style Pokemon show illegally produced by Samson Montford in 1998. The pilot was buried after it triggered a wave of lawsuits, driving Montford into hiding. It is speculated that the whole debacle led to the removal of several Pokemon species from the finished Gold and Silver, as well as Nintendo's harshness in protecting its intellectual properties.
