Furni needed: 

- 1x Pet Horse
- 1x Stack tile (1x1,1x2 or 2x2)
- 1x Horse Jump
- 1x Hedges
- 4x Ice Blocks/Maze Divider (because of limitless resource, I use 2 Maze Divider and 2 Ice Blocks)
- 1x Roller
- 1x Cabbage

First Step: 

Place the Hedge anywhere in your room but I recommend you place it in the corner of your room.

Then, use the stack tile to stack the Cabbage at the back of the Hedge. 

Second Step:

Place the Roller in front of the Hedge.

Then use stack tile to stack 4 divider/blocks on to the sides of the hedge, 2 dividers/blocks each side, this will prevent the horse from running off the Hedge after jumping.



Third Step:

Place the Horse Jump next to the Hedge so it could be closer to use.

Then ride your horse and make it jump through the Horse Jump first. This could drain your Horse's energy. 



Fourth Step:

Now you can slide onto the roller and the Horse will automatically jump in the Hedges. 



After following all the steps correctly, the Booster should be working and you can watch your Horse Jump achievements going up. But please remember that the Horse must be the Room Owner's Horse, or else it will not work. And don't forget to drain the Horse's energy too. If you have problems in doing the steps, you can contact me on Habbo and I'll gladly help you! Hope the Guide helps!
