Freddi Fish is a series of point-and-click adventure games aimed towards children from Humongous Entertainment. The series began in 1994. Freddi Fish is an anthropomorphic yellow fish who takes on detective investigations throughout the series. Her best friend, a green fish named Luther, goes with her on all her adventures. The voice of Freddi Fish was performed by Annette Toutonghi and the voice of Luther was performed by Mike McAuliffe at Bad Animals Studio in Seattle, Washington. The series sold more than 2.5 million copies and won over 75 awards of excellence. In each game there are multiple different possible sets of quests one has to complete in order to complete the game, depending on the playthrough (randomness determines which set of quests the player is given).

Gameplay Freddi and Luther move from one area to another by clicking where the cursor turns into a 3-D arrow. In each area, there are places that the player can click that play an animation that is irrelevant to the plot, including crossover cameos of the other Humongous Entertainment games (Putt-Putt, Fatty Bear, Pajama Sam and Spy Fox), as well as important items to collect (including sea urchins that can be spent as money to buy other items) and non-playable characters to speak with. Some items or areas are inaccessible unless the impediment is removed by helping a NPC or obtaining another item needed to advance. All items collected are kept with Freddi and stored in an inventory for later use, and her ability to carry them all out of sight is left unexplained. The two fish usually journey together, but in rare instances throughout the series, they may be separated and the player takes control of Luther. In such sequences, items cannot be used until Luther reunites with Freddi. It is also possible to save a game in progress so that it can be continued later. Overall, Freddi Fish Junior Adventures are mainly about helping solve others' problems which are tied into a constantly progressing story line.

In all the Freddi Fish games, except the second game (Haunted Schoolhouse), the game is divided into two areas: a larger main game world where the player completes favors for NPCs and gathers and uses items to work towards solving the mystery in question, and a smaller endgame area that is a point of no return where Freddi and Luther lose most or all of their items and confront the main antagonists and finally solve the mystery. The third and fourth games end with a mystery to find out who was the thief. In the third game, they give one or two clues that point to the personality of one of several possible suspects determined at random; in the fourth game, a clue in the Hogfishes' room points to an object the suspect had been using.

Characters Freddi Fish takes place under the sea and features many anthropomorphic sea life, with the adult fish characters being highly anthropomorphized in that they float with their heads raised and tails pointing downward, atypical of real fish, and even wear human clothing.

Main characters Freddi Fish – a smart and courageous yellow fish with orange fins and blue eyes, she volunteers to investigate any mystery or crime that has recently affected her friends. She often counters the crooks she catches with morals of wrongdoings and has a desire to be a police officer when she reaches adulthood. She was voiced by Annette Toutonghi. Luther – a green fish with beige fins and black eyes, he is Freddi's best friend and sidekick. He is a guppy like Freddi and, while being a bit cowardly and greedy at times, he is very faithful to his friends and family and does care about others. He was voiced by Mike McAucliffe.

Recurring characters Boss & Spongehead – two thieving blue sharks who steal stuff specially for the Squidfather.

They appear as the main antagonists in both "Missing Kelp Seeds" and "Haunted Schoolhouse". Catfish – a white fish with the head of a cat and green fins belonging to the Squidfather. Casey – a magenta fish shaped like Luther with the same-colored fins and the same eyebrows as Freddi (even though they are different genders).

Sam – a pelican and close friend to Freddi and Luther. The Squidfather – a pink giant squid, who groans and mumbles when he talks.
