The schmape evolved in response to the rise of the Skroungersaurs, which filled the MEGA BOX!!!1!!111!!’s previous niche, forcing it to escape upwards into the trees, it is also now an omnivore, and is more yellow to blend in with the yellow foliage, it carries its eggs on its ‘tail’ to keep them safe from Pacskrounges as well. It is more intelligent both due to this parental care and because it must now navigate the treetops and determine the strength of a given area of a piss leaf.
