SeaRider - is a plugin which can affect all sides of gameplay from just swiming to last boss fight!
This plugin allows you to tame a squid and use it for swimming or even flying!

Multi-Version compability will added in next update

Features:

You can tame squid with Melon!

No commands
Easy to use
No config. Oops.. That's not feature. I will add it soon.

How to:

*Important: Read "Known bugs" !

Find squid near water surface.
Right Click it with Melon. If you lucky - it will tamed (similiar to wolf)
You can swim over water surface and forget about boat :3
Feed it with Glistering Melon to make it fly!

Each piece of Glistering Melon gives 2 minutes of flying.

Fix some bugs
Teach squid how to teleport through Nether-Portal
Any ideas?

Known bugs:

Dog-bug: sometimes when you taming squid you can see a dog. Thats bug exists cuz spawning dog it's the easiest way to make hearth-partlicle. It will be fixed with 1.8.
Random-moving: Sometimes squids can highspeed glitch to random sides. As I understand that client bug. I don't know how to fix it.
Squids can't dive with you cuz game will dismount you if you go deep. Unfixable.
Know moar?
