I have completed the Pin Flingin' Badge 3 times - and have received the Going Bananas Badge - and have not received the Pin Flingin' Badge. You cannot even complete the 2nd without the 1st! lol BAD SHOW!
2/5. Maybe 4/5 if the boulder level wasn't so damn fast that, even if you figured it out right away, you had to try 20 times. Similar criticism of the basketball level. Too damn fast.
