Hornsby

Hornsby is a male rhino that arrived at Snail, unknown to Tom Nook.

Background
Hornsby, having hitched a ride on a Dodo Airlines plane, hid in the upper areas of Snail before he was found eating the garbage of Reneigh. Taking pity upon the sad sack, Reneigh asked Tom Nook to build a house for the presumed homeless rhino. Taken aback, Tom Nook would soon find a use for the blue guy.

Nook would secretly spike his drinks with corrupted Froot. This permanently damaged Hornsby’s mind, turning him into a degenerate addicted to smelling people. He would run around Snail, begging people to let him smell them. The only person that allowed Hornsby to sniff them was Penelope.

After Penelope's death, Hornsby had enough. He shut himself away. He allowed the cockroaches in his house to fester, and as a result of Froot withdrawal, he hallucinated that they could talk to him. He also began placing his toaster on top of places where it shouldn't have been placed, such as the stove top. He eventually busted out, wrecking havoc on the lives of fellow Snail denizens. He eventually went to Town Hall, charged at KK Slider, severely injuring the mutt. He started to scream about how Tom Nook was a villain and how he destroyed his life

That is when Tom Nook ordered Coa to execute Hornsby. Hornsby was told he would be shipped off to a better island, full of rhinos just like him, but in reality was being sent to a far off glue factory.
