I understand why we would add them to a game, but what would make a sim to have an annoying faery in their shoulder?
Let me sive some ideas to you, anyways (I think they can't be done, but you should try)
Hey! - every half a hour if the sim is sleeping
Look! - Every time a car pass in front the house, especially in that city with tall buildings (I do not remember the name), or every time the sim walks near a ladybug or common butterfly (or even if the beetle is in the same lot or on a nearby one).
Listen! - navi forces the sim to drop the whole task queue... every time it is longer than five
Watch out! - the sims drops the queue, turns around, freaks out, and the "creeped" or "scared" moodlet

Also, it would be good and option to kill navi or trap it inside a gem. Good sims get a bad moodlet, evil a really good one (+50 or +100), and the rest a "peace of mind" moodlet :P
Try making a mod to add all that ^_^

What is the outfit of the boy in the first picture called? I WANTS!

it's not working... HELP WHY DOESN'T IT WORK! ;( I CLICK ON IT AND NOTHING HAPPENS! WHAT ISNT WORKING? *sobs*

AHHHHH OMG. THIS IS FRICKIN AWESOME. Just made my night. xD (yeah I'm totally that nerdy that this made my night... O.O)

wow this makes me wish i had sims 3 but i dont i have sims 2 so....if someonecould make one PLEASE!

Thank you I have been wait for Navi

I love this
*drops dead*

Wow! Thank you so much! I loved Navi in the game, and this is perfect!

:d Get The Fly Swatter!

I installed it and the icons show up in the accessories menu, but even when it's selected, the fairy doesn't show up. Any help?

EDIT: Never mind, I got it. Here's a tip for anyone else having trouble: instead of downloading the pack that has both the shiny and colored versions, just download the shiny one.

That's a fairy like Ciela from The Legend Of Zelda! Cool!

I don't normally comment on the mods I download (creators know their work is appreciated usually). But this warranted it. I Spent countless hours playing this amazing game and listening to the HEY! Listen! Thank you I will FIND a reason to download this. I'm going to make link!

this is great THAKYOU!

:ddddddddddd Zelda <3

I'm not really OBSESSED with the legend of zelda but this is just too cool to NOT download! Makes me wish I hadn't sold my copy of the legend of zelda: spirit tracks :/

nice i like. do you think you could change what category they use because i would like to use this with the master sword and shield i found on my sims 3 blog. they take up earring and glasses

NAVI lolz, i dont even know what navi is, i odnt like zelda much but im downloading nayway cause it is cute

I've been waiting for this since i first got sims 3!! THANK YOU THANK YOU THANK YOU!! YESSSSSSSSH!!

Hey! Listen! Don't go to work, kill that Stalchild! No! Don't get cereal! Find Princess Zelda and SAVE THE WORLD.

Now I can torture my Sims. Muahahahahahha

OMG, I love this! Thank you so much! ^^

So cool! Thank you!

I love you. You are AWESOME. Navi <3333

hey! I know this thread is kinda old but I got an idea maybe you or sb would make an flying futuristic camera/device with this mesh(?). It could be a personal protection for sims and it'd look good I guess. It's just an idea but I'd love to see sb interested it this ^^
(sorry for my english if it's bad)

Yay a shoulder pixie to be your guide!!!
