Finally done!
Just finally completed the last/ first 2 Timed Scenarios so I have all the statues, finally. I've long since completed all the Career scenarios on normal and hard, but I got nowhere with the Timed ones until I started at the last DLC and worked my way backwards to #2, where I stalled out hard. Took about 10 attempts over the last two weeks to finally get #1 and #2 done, and on this last one the RNG was truly terrible - I had to hope a couple of flamingos and black wildebeests would make up the appeal of the giraffe I never did get and draw in the last hundred guests - about 2 minutes before I lost gold.
