Where's Louie the Llama? :(

hey guys i just realized this and you can call me ridiculous for making such a big deal out of it but, where is Louie and Muscles and all the other animals? I know where Bubbles is (he's well and in a place with other animals) but what about the rest of them? one of Michaels tigers, Thriller sadly passed away last year :'( so im worried please tell me, is Louie ok? i dont even know how long llamas live :(

if you know anything about any of Michaels animals tell me
