Lots Of Money
If You have a stud multiplier (x2, x4, x6, x8, x10) Then if you die you get more money then you started with if you collect up the studs from when you died!!!
In gotham metro in the part where you defeat the drill guys use green lantern on the left side of the stage and you will see a green thing then turn it into a punching glove and you will see a mud puddle wash all of the puddles with Aquaman and you will get the minikit.
Azrel uses heat vision

Other way to make the vines go away on Arkham estate
In the start of Arkham estate In story mode you have to make a thing that sprays poison when you turn the wheel with a silver thing but in free play mode you can use poison ivy to remove the vines too without building the thing that sprays poison.
How to get a lot of studs
Go to the Gotham Finland (parking lot) , get in the green car, and break some of the cones it's really easy:) . :( bad news it might take a wile to get there. :) you can go to the bat cave and teleport there.
Weird flying water glitch
I suggest doing it in arkham asylum. so what you have to do is go to the big pool of water and a character with a flying ability and with a swing weapon ability.so you get the character with the swing ability and you hit the side kick with the flying ability and hit them with the weopon in the water. then you'll find out that the character is UNDER WATER FLYING! I suggest for the flying guy to be invincible.
