Um, what is this?

For those who can't read:<br /><br />October 3, 3048<br /><br />I have found an odd creature roaming about the ruins of Underground Prime. It appears to be about 2.1m long and is about 34cm tall and 0.9m wide. From what I can tell, it is a canivorous mammal. The part that cought my eye was its form of locomotion--wheels! (Image with the caption of "This drawing doesn't do it much justice.") Preleminary X-ray revealed a surprisingly normal skeleton.<br />Next page: What I will name this is anyone's guess and how on this planet, God's green earth, or anywhere else this came about is also a complete mystery.
