Yeah dude, I always wondered on these questions, too.
How is it that non-sentient creatures can seemingly automatically transfer upon contact, but sentient creatures seemingly require a morph-capable person to have transfer?!
Maaan, if we go into depths in the world of the Animorphs we'll be like Alice in Wonderland, picturing going down into the Yeerk Pool could be like going down the Rabbit hole.
Also, how big is the Morphing Cube?
To be big enough to be carried in the mouth of a wolf and a buffalo, light enough to be carried by an eagle AND fit 5 palms of human hands on each facet. What proportions would you guys imagine that would approximately be?
Are we talking Rubik's puzzle cube-sized or fist-sized?!
