Hey monkey! Everybody knows that its very difficult to find BT when he is online but has not posted that where the party is going to be but me, creeper405 and xDmackenzie did it. We found BT when he was in BRB at the Lagoon yesterday.We then attended a secret party with BT and the Ray4603 also came into the party as he was also finding BT. Here is the photo of the secret party.
You can also attend a secret party but if you do some effort in finding BT around the MiniMonos island when he is online. Monku20 :-D
