I think it would be pretty neat to have garloids we could grow for food and company, and to show off in our gardens.

Hypothetically, how hard would it be to engineer a simple organism like a garloid? Practically, how hard would it be? It wouldn't have to be made of original genetic codes to qualify - I'd imagine it to be somewhat of a fungal organism with the structure of a pitcher plant (hollow cavity for nutrition) and made of bovine/porcine muscle, fibroblasts, and connective tissue.

Fundamentally, this should just require some bioinformatics and getting animal tissues to organise themselves into a garloidian tube with which they can be fed and grown for milking or consumption (think something like outdoor-grown tripe). I see the reproductive system being something harder to engineer, but we can cross that bridge once we can create asexual garloid zygotes.

Could it be done? Should it be done? Should we do it? Can we do it now?
