Gash is the most powerful attacking pet, the others attacking pets being Itchy, Rufus and Stanley. For every bite, he deals an equivalent damage to a Level 8 laser. Though, he eats one guppy from time to time, so he isn't picked often by players. However, he is more useful in Tank 4, because of Breeders, so losing one guppy is not as big a problem like in other tanks.
If Gash is used outside of Tank 4, Prego can be used to help negate some of the cost.
"Gash used to be one of Itchy the Swordfish's best friends until Itchy left him for dead in a violent alien attack. Now, years later, Gash roams the tank trying to settle the score with the aliens and perhaps one day... with Itchy as well!"
- He is named after a gash, which is a deep cut or wound.
- Gash is one of the three pets which kill Guppies, the others being Amp and Shrapnel.
- Gash is likely based on a great white shark. So he would only take up a small part of the tank, however, his length was made a lower value.
- Gash eats normally one fish soon before and one fish soon after an alien attack.
- Gash does not attacks aliens during final boss battle. Rufus and Itchy don't, either.
- If Presto is turned into Gash, he will immediately eat a guppy. This is likely done so that players won't simply transform him into Gash and immediately transform him back before paying the penalty.
