A little bit of context (since I'm the guy who commissioned this).
All three monsters have an effect to attach other cards as a material.
Harmonizer Gradielle can attach an opponent's monster on quick effect once per turn, so she's a bit more reserved.
Traptrix Pinguicula has a non-once per turn effect that can attach any monsters that were sent to GY or banish zone via trap cards, so she seems bit more opputunistic (aka save the best stuff for latter).
Epurrely Plump has several effects to attach up to 5 cards to itself in a single turn, so it's the gluttonous type.
