Meet Echo Bean! The Interactive Friendship Therapy Bot!

He works with special needs ponies, such as those with learning issues, various syndromes, terminal illnesses, profound cognitive impairments, serious psychiatric problems, and not limited to anxiety, depression, PTSD, various mental health issues and so on and so forth. Has lots of bits and bobs and fidget stuff on it to keep a hors entertained and distracted. Also comes with an in built friendship module and adaptive social learning skills to make sure it's owner is as happy and engaged as possible.

He's certainly not supposed to be something that fights. He is supposed to be a bot that comforts others, but it can become preloaded with fighting/restraining techniques for more 'troublesome'…special needs horses
Say, someone with violent tendencies to lash out on others, or themselves.
