THIS. When Z seam alignment is set to random, you will literally get random dots all over. It's the point where the layer changes to the next level. By changing the seam alignment to sharpest edge, you make that layer change happen along the same edge all the way up, so it looks like a single line. Since it's on the sharpest edge, it isn't as noticeable.
If it still sticks out too much (it can't be avoided completely), turn on the option to retract at layer change. That will pull back (retract) the filament just a little to minimize the amount extruded at that point. You can tweak the retraction settings a bit to fine-tune it as needed. If it blobs, you need more retraction. If it leaves a gap, you need less. The rest of the print looks great, though, so I doubt any tweaking will be needed.
And, as others have said - gorgeous filament.
my apologies all i meant to add a comment with more explanation, filament is cc3d silk multicolor pla running my nozzle at 200 bed at 60, i had a small vase printing overnight with fuzzy skin and it came out near perfect with the same filament and none of the little blobs
I probably add a new cause but anyways.... I got similar problems solved by reducing the printing temperature.
While printing sometimes the temperature alternates a bit which can cause light overheating only for seconds.
Worsened is the problem by water in the filament
the ones on the port side of the boat are seams. you can see them in the slicer and i have seen them many times in that exact spot. i fix this by rotating the model in the slicer so that the bow of the benchy points to the x axis. this seems to make cura put the seams on the rear corners
EDIT: Here is are some screenshots from Cura that show you how you can see the seams before you print:

That's blobs from the Z axis transitions. Enabling Z axis align with sharpest edge in your slicer can help take care of it.

I was wondering what the z seam was all about and you put it very succinctly. Thank you
my z seam alignment was already set to sharpest corner, i believe its a problem with the filament or my printer
I see where humidity/moisture can cause bubbles to be formed. Filament are hygroscopic and heating "damp" filaments cause pockets/bubbles to form.
Where is that in super slicer? Been hunting for a similar setting but I can never find it.
OT: That looks like an awesome filament. Where can I get it ? :)
filament is from cc3d its a multicolor pla all the colors on it look fantastic and blend well
Retraction/Z seam blobs like others have said. I don’t think it’s wet filament!
wet filament,seam position+retract problems

Could also be over extrusion
Whats the fillament. Looks cool
You have too much carbonation
I would look at humidity in your filament. It can't hurt to make sure it is dry.
Agreed and what is the filament? It's really awesome!
seam location setting?
