I have been trying to get this to work. I am using both version of the farmer posted.
Medusa egg farmer (newest).
Hit play, finds hole, walks to hole, uses flute, new target system reticule flashes around a bunch, then the cursor hangs and rarely selects a snake. When it does, it is almost always out of range. After this, the script always seems to select the same snake and the cursors hangs. When it DOES click the snake, then second target will just click a random spot on the ground.
