I’m working on something very similar with some of my Toa MOCs, but instead of creatures being attached its more of a backpack with underwater gear, e.g. air canisters, propellers.
Are they accessories related to the Creatures, or just random whatevers?
I mean, it sounds cool either way, but it would make sense to have mechanical things to do similar things to the Creatures.
They’re not sentient, just basically scuba gear, but unique designs for each Toa. And i should mention that they aren’t the 2016 Toa, completely my own design, so only really relevant in the sense that they also have the combining feature.
Main difference is that i try to make the attachment look separate, by having the Toa use no silver at all, while the attachment is primarily silver.
Might start a new discussion with some pictures of it if you’re interested. I’ve only got one finished right now.
Lego has technic-heavy fails like Skull Scorpio and technicless fails like LB.
Soooo…
This^.
To use my latest MOC as an example:
The legs and one arm are simple enough, just basis CCBS. I could have gone for custom, but it would have just been an unnecessary strain on my limited parts reservoir. On the other hand:
Custom feet because I had no small feet.
Custom arm was necessary to have the claw feature and not look awkward.
Semi-custom head because hair.
Custom torso so I could achieve the look I liked.
I used custom when needed, and when a CCBS bone would work, I did that.
