I wonder what the intended age group is. These animals are a bit scary - imagine an infinite row of sharp teeth and infinite number of tentacles going after you (on the bright side it would take infinite time to mobilize them all); i got scared by the yellow submarine as a kid, interesting if real kids like it.
