People always seem to get very confused about the artic awards! :laughing: Hope this sorts it out:
"Penguin Colony" (silver plaque) - displaying 16 emporer penguins in a highly suitable exhibit (don't know how high it has to be... 90 maybe???)
Reward = $5000
Excellence in Arctic Conservation - displaying a beluga, walrus, narwhal, arctic wolf, polar bear, and jellyfish in highly suitable exhibits
Reward = $25000 (this does NOT unlock the iceberg!!!!)
Excellence in Arctic Construction - displaying a beluga, walrus, narwhal, jellyfish, arctic wolf, polar bear, wooly mammoth, and wooly rhino in highly suitable exhibits
Reward = $500 000 AND the iceberg!
It seems the last two are always confused, so make sure you're thinking of the right one when trying to unlock things! :original:
