Panel 1: We start off with Elly's disembodied head hovering over Mike and Lawrence and yelling "ABSOLUTELY NOT!! YOU TWO CAN WALK TO THE PARK FROM HERE!!!!" The reason for that is that they want to play hide and seek in her yard and disturb her while she's gardening.
Panel 2: As she unhinges her jaw and points her hand in the air, she bellows "IF YOU TWO DON'T START USING YOUR LEGS, THEY'LL SHRIVEL AND FALL OFF FROM LACK OF USE!!!!!!!!"
Panel 3: The two of them stand there goggle-eyed as her silhouette goes off to bellow at John because of his evil plan to have children play in her yard.
Panel 4: They then look at their legs; Mike asks Lawrence if he feels anything yet.
Summary: I feel something: disgust. That's because Elly is so crabbed up, she can't let two healthy, active kids play in her presence; eventually, her yelling NO!!!!! all the time would turn Mike into the slug sitting on the couch keeping her from watching her stories.
