During Alice's first visit to Wonderland, the Fish Footman was responsible to deliver an invitation to the Duchess from the Queen of Hearts for a game of croquet. The Frog Footman revives the letter as they both greet each of getting their wigs tangled up. After getting untangled, the Fish Footman leaves and the Frog Footman sits down and doesn't bother delivering the letter as he plans to sit here for days and days.
American McGee's AliceEdit
The Fish and Frog Footman were planned to appear in American McGee's Alice, but never made it to the Final Cut. It is unknown if these characters were planned to be enemies/minions of The Duchess or residents who would aid Alice on her quest. It was described that the Fish and Frog Footman can be dealt with together, as they are essentially the same character but with slightly different appearance and voice. A remnant of Wonderland's peaceful days, the Fish and Frog Footman wander hopelessly around the Wonderland Woods. The Footman will follow you peacefully, but if hurt they will draw small daggers and enlist the aid of Card Guards.
Alice: Madness ReturnsEdit
Concept art of the Fish and Frog Footman can be seen in The Art of Alice: Madness Returns and a Model of the Frog Footman can be seen in the Extra Content as it states, "His appearance (formal) and intelligence (modest) were not required for this adventure. He's still a good frog." This could mean the Frog Footman was scrapped once again or he ended up as a random character in the background.
