If you have sound on, you can hear a familiar crashing sorta sound when he leaps up.
If you dont? Uh oh
keep ya eyes open! & oops you jump the moment you see/hear him leap up.
I find the stupid -3's & -2's most annoying. Not only do they make you lose laff points they make you fall over & takes all the getting-up-again time he needs to close up his undercarrige
