The others are all crazy.

IF we're talking girls. I prefer to stick to slash, myself. Also, Veronica needs to admit to herself that she actually loves Trixie.

That said, Cindy and Jimmy actually hit it off when they meet, and continue to get along forever after. I never like crossover pairings, but somehow...SOMEHOW...this one manages to work. But it won't happen since it IS a crossover pairing, and the Jimmy Neutron team became fixed on Jimmy/Cindy romantic drama. If not Cindy, Trixie would be surprisingly decent for Timmy. She's shown the ability to be down-to-earth and real. If she managed to stop caring so much about how people saw her, she'd actually be a great match.

Never Tootie. NEVER.

In the Nickelodeon movie Timmy falls in love with Tootie.Duuhh.. He kind of likes her but he doesn't know it.
Trixie has a big idea for herself.
Veronika is stupid.
Vickie has lost her mind.
Cindy, oh she, she is in love with Jimmy Neutron.

This is ny opinion. Don't judge me (or even if you do, here is a little secret: I do not care what do you think of me, i just love being my self and tell what i think.)

CINDY ALL THE WAY!!!!!!!!!!!!!!!

None actually. No one of those girls are deserve with him.

Trixie is a snobbish popular girl and she hates him.
Tootie is in unhealthy obsession with him.
Cindy is from another show, I ship her with Jimmy Neutron.
Veronica has the same case with Trixie
Vicky? Eww..

I'd prefer Missy (unfortunately she only appear in one episode) or Chloe Carmichael for him.
