Welcome to Radio Galaxy Zoo, science rules 101 (cool name)! 😃
That 'little spot' is a brighter part of the radio sky, but not bright enough that it triggers the software to draw a contour around it. Perhaps it's just 'noise', perhaps created by the way these radio 'images' are created (a method called radio interferometry).
If I move the slider far to the right, so the radio part becomes invisible, I see that the 'little spot' coincides with a faint IR (WISE) source. So, this could be the core (radio) or host (physical, IR) of the main source in the center (it's a teardrop shape, or a lobe). However, as the thin end of lobe is at ~the same position as a galaxy with a redshift of 0.452, SDSS J103812.90+071907.2, I think this is more likely to be the host. That would leave the little spot as a compact radio source, with the host being the faint IR object, or it perhaps being merely noise.
Hope this helps.
