I like animals. Especially armadillos. I know they are native to the Americas.  Do they make good pets?  
I've never heard of that animal. Are they a carnivore or a herbivore?
I'm not sure of their diet.  But I suspect they are either herbivore or omnivore. They are identified as mammals. 
Are they an endangered species as I've never seen one?
Endangered species
An endangered species is a species which has been categorized as very likely to become extinct in the near future. Endangered (EN), as categorized by the International Union for Conservation of Nature (IUCN) Red List, is the second most severe conservation status for wild populations in the IUCN's schema after  (CR).
In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered (EN) worldwide. The figures for 1998 were, respectively, 1,102 and 1,197
Frugivore
A frugivore is an animal that thrives mostly on raw fruits, succulent fruit-like vegetables, roots, shoots, nuts and seeds. It can be any type of herbivore or omnivore where fruit is a preferred food type. Because approximately 20% of all mammalian herbivores also eat fruit, frugivory is common among mammals. Since frugivores eat a lot of fruit, they are highly dependent on the abundance and nutritional composition of fruits. Frugivores can either benefit fruit-producing plants by dispersing seeds, or they can hinder
