It's now official - the number of pet baby iguanas being flushed down the toilets of homes by irate Korean mothers has led to huge numbers of iguanas breeding up in the sewers of the city, and now overflowing out onto the streets where they enjoy feasting on garbage bags. At least, the situation isn't as extreme as those baby crocodiles grown up and now nipping at the heels of city residents in New York, residents that is who are brave enough to approach open manholes and garden ponds. What to do about this urgent situation?
