One of our players made a good point recently - it may not be obvious to everyone that My Little Pony characters only average approximately 3-4' in height (hence My Little Pony). Whether the average pony height is closer to 3' or 4' seems to be a matter of fandom conjecture, but you get the idea. This is one of the reasons why we do not allow characters that exceed 8' in height - it's rather unlikely such characters would be able to move about easily on the station. The 'Apply' tab has been modified accordingly, under the 8' height restriction in 'unacceptable character types'.
Helps to know, especially when you're not playing a pony!
