The alien babies
Milton headed over to his new gym and had the pool part redecorated.

He added a dance studio to the other part.

He got home in time to see the babies grow to toddlers and got the fright of his life.

Not only did Mabel have no nose to speak of, her head looked like a skull from the front.

Unfortunately I couldn’t get in close enough. I thought I had a pic of Miller, but it seems not (and I emptied the recycling bin into which I’d put the pics). He looked like a grumpy old man.
Milton decided to go back to his original plan which was to adopt a school age child (as his heir) and get rid of his alien offspring. Their birthdays were fast-forwarded.
Miller on his next birthday:

Mabel on her birthday:

They were too horrific for Milton to tolerate so they were both drowned in the indoor pool. I think Muriel Snipes was quite relieved.
Now the aliens were out of the way, Milton rang up the adoption agency to adopt a more normal-looking child.
