Eggman started bouncing forwards, the arms pointed downwards so the spinning blades could damage Lina and Alex. Alex ran forwards and ducked under the blades. When he was behing the Egg Mobile he jumped and punched it. It flashed for 5 seconds and made it's damage sound. That is when it bounced high into the sky. When it went down Eggman aimed to hit Lina, she posed more danger to him than Alex Kidd.
