Taco 🌮 (she/her) — A witty, secretive taco who initially presents herself as a goofy and unpredictable contestant. Beneath that silly exterior, she is highly intelligent, manipulative, and determined, often using clever strategies to get what she wants. Despite her darker side, Taco has shown that she genuinely cares about certain people and is capable of forming meaningful friendships.

TikTok 📱 (he/him) — A social-media-app contestant in Battle for Niche Internet Fame. TikTok is energetic and trend-focused, with a youthful, fast-paced personality. Despite his confident internet presence, he can be easily intimidated, especially when faced with something genuinely frightening. He is voiced by Chip “UltimateLazyBoy” from Episode 2 onward.

Pepper 🧂 (she/her) — A ditzy, stubborn, and somewhat egocentric pepper shaker who is extremely close to her best friend, Salt. She often speaks with lots of “like” and “OMG,” eagerly follows Salt’s lead, and can be surprisingly vindictive toward those she dislikes. Despite her dependence on Salt, Pepper has become more independent in Season 4 and is determined to do things for herself.

Topaz 💎 (he/him) — A kind, sensitive, and optimistic orange topaz gemstone. Although he can be a little naive and pathetic at times, Topaz usually tries to see the best in everyone and prefers using reason to solve problems. He is close to Toy Train and often serves as a positive influence on him.
