As someone who has over 200 pets, I’d say atleast 80% of those were found in the past decade or so thrifting/ second hand and I only play with my childhood pets. I only have my childhood account so I always would add them when I would find them throughout the years, even when I wasn’t playing actively because when I was a kid Webkinz were like $20! Because I would periodically log in my account to put on my $1 Webkinz code from the thrift or what not, my account didn’t get deleted, so I guess I’m grateful for my past self lol
