about badly rigged squidward man

this is one of the two things i was working on

it is about badly rigged so you just need to tweak the rig or keep as it is then click the squidward thing then click the armature with the shift key and left click at the same time ( you need to click the two circles next to the arrow and the circles that you select shading from and also under the word geometry nodes to see the armature ) then click ctrl and P at the same time and choosee parent with automatic weights and blender might crash so you might need to decimate the model and please resend me the blend file after you rigged it for free or i will keep speaking to you as if you were a beginner
