U55 Our Junior Bullfrog Won’t Swamp Your Budget!

Scaled-down somewhat from our Great American Bullfrog (Z55), our just-over-life-size adult female Bullfrog Junior embodies the same attention to fine anatomic detail and rugged American-made quality, but is intended to keep your head above water budget-wise.

Life-like sculpting and vibrant hand-painting faithfully portray the same ten organ systems found in its big sister, but with fewer numbered features and no detachable parts.

Molded of non-breakable vinyl plastic, Bullfrog Junior lifts off its hardwood stand for hands-on pass-around study. Hand-numbered features - more than 100 in all - are identified in the accompanying key which also includes a fully-labeled illustration of the reproductive system of a male frog.

Overall dimensions: 17x11x4 inches (43x30x10cm)
