Mickey tries to rescue him before the doctor can perform his experiment: putting Pluto's head onto the body of a chicken in order to see if a puppy will hatch from an egg.
The scene then fades to Mickey asleep in bed and suddenly woken up by a fly, whose buzzing resembles the whirring of the saw.
[10][11][12] Other analysis purports that the short is an examination of "the machine age and its discontents" as Mickey encounters the "horror of science technology" when facing The Mad Doctor.
The Mad Doctor character is in the public domain in accordance with his appearance in this short under American copyright law.
A photo of the Mad Doctor can be seen on a hospital wall during the Roger Rabbit short Tummy Trouble.
[15] In 1988, a cel from the short featuring Mickey looking down "a staircase of skeletons and included the background scenery" sold at an auction for $63,800.
