Right off the top of my head [& I'm not a foley artist, so you'd have to work out the details]
elements...
sharp points to feet - high transients
lots of legs - 'skittering'
rhythmic walk - pattern that could become 'signature'...
& don't forget ...big, so lots of things dropped an octave, added subs
'skin' movement noises, not synced to ...

No one sound is going to do this, to get this right your effect is going to need to be a composite of several different layers. Your celery idea might form part of one layer, but is never going to do the whole job.

Low ground rumble (sub)
Dirt/soil movements
Roots snapping
Wood tearing/splintering/creaking
Branches scraping
Foliage ...

Divide the sound into at least 3 layers/concepts: low (wood resonances), mid (mud), high(celery) (freq) or mass, force, strain,...

Clearly from what Arnoud has said, you need to meet the character defined by your visuals. Having said that I'd be inclined to be fairly literal here and record the sound of you pulling some plants out of soil. If you can get the microphone in nice and close you should get a nice proximity effect that when boosted up should give you the impression of ...
