"Look! A squirrel!" is a common distraction trope. Like when you try to concentrate on something and get distracted with something banal. It originates from dogs being easily distracted by squirrels and forgetting what they were supposed to be doing. Often used on purpose, for example by politicians announcing something irrelevant to drive your attention away from what matters.

In this case, robthebold distracted himself and the "squirrel" was the bee. At least that's how I read his post.
