Ok... so no idea what the hell happened... but I made a reply... I swear i did.... i remember writing it. i remember hitting post.... I think i may be losing what little mind I have left. for what ever reason im sorry the reply never posted. Now on to the questions.
I already have that planned for Zootopia but i wanted to give you a chance to respond first before I did a little mini text vomit. I got a nice little story to tell. I also have some ideas for furnature...but if you want anything specific feel free to add it.
I think that would be an interesting meeting and would love to see the two characters cross. but that opens up a whole can of worms I dont want to get into, also not the biggest DMC fan, tho i did enjoy them a little. But still very interesting to see what would go on between them.
For FNAF we could just have a little bit of a play session where Foxy watches Mika build... maybe he even starts huming his little tune for Mika.

As he picks her up to take her to her bed, she ends up cuddling against his chest, listening to his servos like a heartbeat and ends up sucking on her thumb as the sounds lul her to sleep.
As for Naruto... you could gloss over it if you want. Or I could do a little temp control. Maybe even have him realize whats going on to an extent with Naruto and Kurama and realizing the playing field has changed.
