You can rent the polar bear from Lost for only $3390, or this cute fake mosquito for $1137.50.
Famous for exploding in a Tobasco Sauce commercial. This oversized mosquito is a foot long and stands about ten inches high! The detail is biological studies-correct. Kids are attracted to this display, they can see the details so easily. Each part of this creature is assembled with great care. The castings are done in translucent resins that are realistic to the touch.Link (Thanks, Kirk!)
