Mr Grr and Mr Arr

Mr Grr and Mr Arr (Mr. Grr and Mr. Argh in Viggo's Revenge) can be found in Secret Island. They are the result of a backfired experiment on General Viggo's part. Bungalow will need to defeat them whilst also knocking the bell to give him extra time before the circus turns him insane.

Strategy
The first thing to do is to get rid of all the bears in the area, since they are all Brown Bears, and a group is a problem (not to mention taking 9 damage each shot). You can get rid of them by climbing up the tower and killing them, then you can focus on Mr. Grr and Mr. Arr. Try to ring the bell at a minimum times, since after you ring it, you will fall and take fall damage (try ringing it when there's only 10 seconds left before death). There are no Pet Yums in this area but there are on the outside of the funhouse (the area in which you came in from).

Also, if you stand on top of the bell, you will ring it constantly. However, you cannot reach Mr. Arr and Mr. Grr. Fortunately, though, you can stay on the bouncer and get hit by the bell constantly, and you can reach them. They cannot reach you, and you will be ringing the bell nonstop, giving you an easy victory.

If you are low on health, you can try sitting on top of the bell and attacking (though it will be significantly harder to reach them). Or you can get on the bouncer and stay in a position where you will continually hop up and ring the bell without having to move, and use explosive weapons to defeat them or grab some Pet Yums on the outer area.

Trivia

 * Mr. Grr and Mr. Arr are parodies of two assassins named Mr. Wint and Mr. Kidd from the James Bond film, Diamonds Are Forever.
 * If the Invulnerability cheat is on and you enter with a character other than Bungalow, you will constantly take damage, though no health will be lost due to the cheat. If one were to make it to the bell area with Mr. Grr and Mr. Arr, they would notice that the Funhouse also deals damage to the enemies as well. The timer is also absent in some versions of the game.
