This is an image manip, based off on the Quicksand scene in the special 'Spring Breakdown'

Rainbow Dash has just ran off from the rest of the group, going deep into the jungle, and Sunset shimmer and Sci-Twi followed to see if they can get her to come back. They followed her deep in the jungle, and then found her, but waist deep in quicksand!

They rushed in to try and save her, but uh oh, they accidentally rushed in too far, and now their feet are stuck in the same sticky and sucking mud, and like Rainbow Dash, every time they struggle and try to free their feet, they end up sinking deeper.

Now how will all 3 get free?

(They really should have gotten stuck alongside Rainbow in the actual scene)
