If you could have any pet that includes extinct and mythological creatures - they also will somehow not be dangerous for purposes of this question - what pet would you want?
I would pick a Hippogriff, id get to flyyy ;3
Bought long ago but never had an account with hunter level to use until now, very simple script works 9.4/10 https://gyazo.com/eddd9a0f86cbe93bb34654b133d83fa2
edit: randomly decided to run away from chins and into ogres and lost over 1k chins :\
Ive not used it much but some other things its done - it kept turning run off and on and not moving until i reset it, got stuck upstairs in varrock east bank too.
Usually its fine, i was buying feather packs, i was seeing gp slowly going down, when i turned off disable rendering to transfer feathers i saw a bunch of feather packs on the ground and no feathers or money in inventory.
Script usually works fine until last time i used it, first time i actually used disable client rendering with it and it ended up dropping all my items it bought for some reason.
