There are 5 BMJack NewVenezia secrets. BMJacks are bots that are hidden around NV. Be sure to get very close to the BMJack in order to collect the secret. Ignore what he says about a "secret code". He is referring to the code for the RED BUNNY, which is listed in it's tutorial. Also, a few BMJacks sell special items; Black Hole, Train Tunnel, and ET Red Bunny.
Evil Twin Red Bunny
Teleport to Evil Twin and walk to the back of the BLACK side. Jump up onto the RED BUNNY and type " /code vside rulez supreme ". You will be teleported to the first of two BMJs.
Now jump over to the next RED BUNNY and once again jump on top. This time type " /code 9 ". You will be teleported to the next BMJ. He likes to dance, maybe you could join him!
Evil Twin Blue Bunny
For this you will need the WHITE VSIDE SHIRT from Evil Twin WHITE (The one I'm wearing in the pics). Go to the back of Evil Twin BLACK to the BLUE BUNNY. You DO NOT have to jump on top, just walk through it. (If for some reason you are unable to walk through, leave the store and try again. You may even have to change outside of the store, change back, and try again.) This will teleport you up to the BMJack.
*You don't have to own the shirt. If you know someone who has one then you can teleport*
Train Tunnel
Go to the train station and head toward the stairs. Go up the RAIJUKU stairs.
Once you reach the top, jump the rail and head for the tunnel.
Crates
Teleport to Kitson and head to the side. Go toward the back and fall into the water.
When you land, walk to the edge and jump down. Again, walk to the edge and jump down.
Walk to the edge. Look down and you will see the crates and the BMJ.
Black Hole
Teleport to Ringo ( type /tele Ringo) and walk outside. Get up on the rail and jump onto the ledge alongside the building.
Follow the ledge and turn right. Down the rabbit hole Alice!
Walk toward the bunny. You will then be teleported to the BMJ (He's behind you).
