1. An animal very similar to the iguana. Main differences include: wears a gold chain necklace, wears FUBU products, carries a gat, uses word like "yo", "hell to the no", "you trippin'", "nigga be crazy", and "word up ma homies on da streetz"

2. An african-america iguana.
Niguanas aren't found on any islands, they don't know how to swim to any.
