Big horse that needs a name

Tommy Rowan has an article at Philly.com about a yet-unnamed police horse:

The New Castle County, Delaware police department is asking county-based elementary school students, in grades three through eight, to come up with a new name for their Clydesdale, a five-year-old draft horse, which joined the department's Mounted Unit in December of 2014.
The department wanted to rename the dark bay Clydesdale (photo), originally named Tyson, due to a clash with the similar-sounding name of another horse.
"Although we like his name, we are changing it so that there won't be any confusion when it comes to feeding or medicating them,"according to the contest flyer.
Students are asked to include an essay that explains the reason behind their suggestion.
The deadline for submissions is 9 March 2015 at 4 pm.

Rico says he hopes they come up with a good one. (Nothing silly, please.)
