Maraschina

Maraschina was a relatively normal girl until a fateful industrial/magical mishap somehow turned her entire body into a strange gelatinous material! Unlike other 'slime girls' however, she didn't just turn into a walking puddle - she still has skin, bones, internal organs, the whole works - she's just see-through and very, very squishy and flexible!

Yes, her new body lets her fit things down her throat, or potentially other orifices, which are far larger than normal. Yes, you can see whatever's in her belly until it digests, or even push things around inside her with your hand, but the only way to get anything swallowed back up is the way it went in, or possibly out the far end if she's entirely unable to digest it (anything digestible just breaks down and seems to vanish eventually). And yes, her squishiness means she could be crammed down someone elses' throat or such as long as they could handle the mass of her body.

She typically only wears light clothes - though her unusual flesh doesn't drip off or make a puddle anywhere, it does tend to attract condensation from the air pretty easily and she gets uncomfortable when dry, so bikinis or other swimwear are usually her favorites.
