Buttercup is a pygmy pony robot, It can be found wandering around in Doc Mitchel's House
Buttercup is not a true companion. It is a slave that is essential 
Buttercup addresses the player as Master or Mistress
If told to Follow Me it follows quite close

There is a Wait here command with two choices: 
1) Don't Move 
2) Just do your own thing (Which means Buttercup will wander around the cell it is in) 
You may have to exit the cell before his sandbox will start

There is a Let me see your equipment dialogue option (Buttercup can carry about 200 lbs)

Once Buttercup is following you, you can ask it about his tactics. 
There are two Tactics choices: 
1) Use ranged weapons (It will attack with his laser eyes) 
2) Use melee attack (It will attack with his hooves) 
Buttercup will use his area effect fireburst spell when his health drops to 90%, 80%, 70%, 60%, & 50%
In addition to the fire damage, anyonee in the area affected by the spell will also be knocked down
The area effect spell WILL hurt the player if you are too close

There is also a never mind and speak freely dialogue option 
(speak freely is left over from the slave script and your only choice is to end the conversation) 

I have also made a JIP CCC avatar.
