This card's name, "Kuriboh" roughly translates to "chestnut person" in Japanese. It is also the Japanese name for the Super Mario Bros. enemy known as "Goomba" in the international version.
Yudias Velgear is currently the only protagonist to not use any counterpart of Kuriboh.
In the Yu-Gi-Oh! anime, this monster self-destructed on contact with the enemy.
The effect of "Detonate" to destroy as many copies of this card and "Kuriboh Tokens" the player controls references this, which works best after using "Multiply", another card that specifically supports this card.
In the anime, this monster seemed to be different from other monsters, as it was almost sentient.
Kaiba called this card one of the weakest monsters in the game, due to its low stats.
However, this card often prevented Yugi Muto/Yami Yugi to take battle damage that would have caused them to lose the Duel.
In the manga, this card's apparent weakness was such that in Yu-Gi-Oh! Duel 131 (Duelist Duel 72): "Attack of Chaos", even Pegasus was shocked that anyone would use it in their Deck.
In an interview in the Swedish Shonen Jump magazine in 2005, Kazuki Takahashi referred to this card as his third favorite monster. In his commentary, he also said (freely translated): What does that look actually mean?
This card's third OCG/second TCG artwork is taken from Yu-Gi-Oh! Duel 104 (Duelist Duel 45): "Crisis!", specifically from the panel showing this monster and Dark Yugi (directly before Dark Yugi activated "Multiply").
