@RamistaR:
I do not deny that Trebol can use Haki but where do you see Haki on that pic?
The same effect are used when [Luffy punched Bellamy](http://img.mangastream.to/manga/one-piece/232/One Piece - 232 - 18-19.jpg) back in Mocktown.
In quite few places since time skip Oda uses effect of sparkles in consistent way when Haki is presumably used.
For example here
! or here around Wadasumi hand
!
also here at bottom left panel
! or even here
! same graphic effect everywhere where CoA is involved and also same thing is visible on page with 3 of Doflamingo seats kicking away Dressrosa soldiers. So I assumed that if Oda is so consistent with this effect lately we can assume its how he hints towards haki being used. If thats the case then in clash of Sanji and Vergo - few pics above - it was leg vs leg without strong CoA haki imbued.
Razh- you wrote about Trebol in way that made it look like statement so I replied with that in mind.
As for argument about him being a logia because of head twisting, changing shape etc Luffy can also twist, bend and strech in unnatural ways for me Trebol looks he is made out of something flubber-goo like thing
yet still with a body not of a logia but paramecia.
Logias for me till now were closer to elements that are meet in nature - snow, ice, fire, electricity, swamp, gas. In last chapter Trebol was shown twice to do something kind of like Luffys gomu gomu no rocket as he used in a way properties of his body being a bit rubber-like by shooting himself in some directions.
Sticky fruit does not feel like logia for me.
