I finished the om in 25 mins and didn’t get the ark, but nvm! I missed pegahoof for just 1 spot in the roulette but nvm! Can’t I take another mission egg doing again the om? Coz I tried and I didn’t get it 
no, unfortunately, you cannot
Doh so I have no chance to get pegahoof but through golds thank you anyway 
U can buy one for 298 gold in the shop and try ur luck again?
