One Hundred and One Shark Pets

101 Shark Pets is a DSiWare pet-raising simulation game by Teyon. As the title suggests, the game has the player taking care of a baby shark pet. This was done by keeping the shark's statistic (health, food, drink, bladder, etc.) high enough. In the meantime, there are various mini-games and the sharks can be trained for shows in which the player earns money to take care of the shark.

A few months later, Teyon released the same game but with dolphins, 101 Dolphin Pets.

Tropes:

 * Amazing Technicolor Wildlife: Some of the color schemes for the sharks are very bright (e.g. you can adopt pink sharks).
 * An Interior Designer Is You
 * All Animals Are Dogs: Taking care of the sharks is similar to taking care of dogs, given that you are also taking the shark on a walk (or swim).
 * Everything Is Even Worse With Sharks: A rare inversion.
 * Guilt Based Gaming: Surprisingly averted, the game doesn't even run on real time. Though the meter depletes faster than most pet simulators.
 * Fluffy the Terrible: If you want to.
 * Mini Game: There are lots of them.
 * Not Allowed to Grow Up: The shark will always stay a baby.
 * Ridiculously Cute Critter: The sharks.
 * Rule of Cute: One of the driving force of the game.
 * Video Game Caring Potential / Video Game Cruelty Potential: You can either torture your shark or you can pamper and care for it. The summary of the game in the official site seems to indicate for the latter.
