Bests & Worsts Reviews from Amazon

When deciding whether or not to purchase this as a gift for my animal-loving son, I was a bit skeptical of another review from a ‘biologist’ that took issue with a card that supposedly stated that penguins were mammals from the Arctic. Since penguins are birds and not mammals, I found it odd that their main issue was the term “Artic”. Isn’t the former error more egregious? Searched and searched and couldn’t find any pics of that card so when I purchased this set anyway first thing I did was go to look for that supposedly faulty card along with the hippo card. Photo attached - none of the errors mentioned in that review appear on the cards. Perhaps they did once, or perhaps they never did. In any case, you can now be confident that all cards are factually correct AND the game is very fun!
