Aaahh!!! Real Monsters (1994)

S4E23 Showdown

Simon the Monster Hunter enlists the help of three of the world's top hunters to track down Ickis and demonstrate that monsters are real. However, as they quickly realize, capturing Ickis is far more challenging than they expected. Frustrated by their struggle, the hunters let their egos take over, rejecting Simon's financial support and deciding they want to do much more than simply catch Ickis.
