OMG, MOST IMPORTANT Q's EVER

Totoro-san!!! <3

I love that movie so much, it's my chrome theme, and I have a totoro plushy~ ^-^

Let me start by saying im a 14 year old boy in high school and i still love both those movies hahaha!
My personal favorite is My Neighbor Totoro but The Cat Returns is really good too. I would get My Neighbor Totoro but its up to you. Good luck in choosing haha. :)

I personally think you should go with Totoro, just because that movie is like one of my favorite things in the entire world.

My Neighbour Totoro.

Personally I would go with My neighbor Totoro, thats such a cute movie, I love it

The cat Returns!
I never got how the other one went, I don't see the plot

Honestly, I haven't seen either one, but I've heard of My Neighbor Totoro, so I'd say to go with that one. It sounds and looks cute. I, too, may eventually cave in and watch it. It's definitely one of the few on my list to watch. I've seen Howl's Moving Castle and Ponyo, which I believe is made by the same person, and it was a great movie, so I suggest them all to you. :)
