Here's a couple of bugs.

1) Mine/Sticky Mine Timer

What it is:
The mine or sticky mine does not activate at the end of the turn.

How To:
After you drop the mine, or throw the sticky, you jump into the water. If you hit the water before the timer reaches 3 (your hog will be accepted as dead before the timer reaches 0 and your turn ends) the mine/sticky mine will not activate. If the next person also happens to die like this during his turn, the mine/sticky mine will still not activate in the turn after that.

2) The Minor Bird Bug

What it is:
You are unable to fly with the bird.

How To:
Just keep mashing the space bar really fast while the bird is picking you up. This will make you drop an egg as soon as the bird picks you up, and will, for some reason, cause the bird to drop you, making you unable to fly further.

3) The Major Bird Bug

What it is:
A funny bug involving activating the bird just before your turn ends.

How To:
You select the bird, and wait for the timer to run down. When one second is left, you press space, activating the bird. Three things can now happen:

a) A box is dropped after your turn, and nothing special happens.

b) If the hog which is next, after your turn is done, is higher up than your hog, the bird flies to your hog, but then slowly drifts downwards, rendering all hogs unmovable although turn time goes on, and the turns continue normally. Hence, the game needs to be restarted.

c) If the hog which is next, after your turn is done, is at the same level, or lower than your hog, the bird flies to your hog, and then slowly drifts downwards. However, when it reaches the level of the hog whose turn is next, it suddenly appears next to him, and he can fly with it and drop eggs. After he lands, three other things may happen:

c-i) The turn ends. This happens if the hog ended it's previous turn equipped with a weapon, like the bazooka, which only has one shot per turn, and still has ammo left of that particular weapon.

c-ii) The hog is free to move and do it's turn normally. This happens if the hog ended it's previous turn equipped with no weapon. This can happen either by just not selecting a weapon, or if the hog uses a weapon in its previous turn, of which it only has 1 ammo.

c-iii) The hog is free to move however it's weapon has been activated, and it is forced to use that weapon. This happens if the hog ended it's previous turn equipped with a weapon which has multiple shots, such as the shotgun.

Note: Neither the team which activates the bird, nor the team which ends up using the bird actually uses up its bird. However, the weapon equipped in the previous turn of the hog, which flies the bird, is used once, regardless of it is ACTUALLY used.
