Update: Some people are already getting their free energy drink coupons! This one came fast and it’s still available
This one doesn’t appear to work via mobile, so you will need to go on a computer to get this one.
Get a Free Java Monster Energy Drink or Free Java Monster Collectible Cup. To get started click here and put in your birthday. Then click the share screen and invite your friends.
It might only show you a limited amount of friends, just click any letter of the alphabet and every name starting with that will pop up so you can invite as many people as you want.
To get the free energy drink you need to invite 25 and for the free collectible cup you need to invite 50. I went for the free cup!
