Firstly, this is not official, so don't get overly excited.
Recently while watching the Puppy Bowl ;D, I knoticed that Animal Planet is seriously hinting at a sixth season. One commercial featured Sea Lampreys and was for Monster Week. Also, during one of the "Animal Planet, Suprisingly Human" logo thingys, It briefly showed Jeremy Wade's eyes.
I don't know if this means anything, but it was tantelizingly like a teaser type promotion. Also, I really do think we will be getting a sixth season, River Monsters is the most popular Animal Planet show ever.
Looking foreward to it!!!!!!!!!!!!!!!!!!!!
Tell me your thoughts below.
