Princess Monster Truck is an Instagram-famous rescue cat known for her severe underbite and protruding lower fangs, which give her a uniquely fierce yet adorable appearance. Found on the streets of New York City by artists Tracy Timmons and Joseph Villela, her distinctive look quickly propelled her to internet stardom. The meme typically plays on the contrast between her name 'Princess' and her 'Monster' visage, often featuring captions that highlight her mock-ferocious nature or her regal demands. It has become a staple in the 'ugly-cute' animal meme category, celebrating the charm of unconventional-looking pets and the joy of animal rescue.
