What might cause a tree to slide down a jet would be if its stocks and shares took a dive in the market. This tree was on a jet for an important investor meeting when it got the news that its stocks and shares had just plummeted. Being very upset, the tree got up and got on the emergency slide out of the jet and plummeted into the ground just like his stocks and shares.
Once the tree hits the ground with his stocks and his shares, the impact creates a large KABOOM (かぶ)! Stocks hit the ground - KABOOM! Shares! KABOOM! Tree! KABOOOOOOM~!
