So there is a website that is called freesound.org that host a humungous amount of samples that registered users upload and share.
It is pretty much a treasure trove of sounds of any kind from instruments to animals etc. and most of them being open to use freely.
In either case Zoundle is a plugin that will help you look for samples according to certain criteria and get them imported directly into your DAW.
This of course being easy to import to your device later...
To download the VST go here and scroll until you find it:
and for people that have not been to freesound.org before it is recommended to have visited at least once:
