Card Appearances:Baggy Pants Lavasaurus
- In episode 11, Scorch uses this card during his Tag Duel with Chills against Yuma Tsukumo and Shark. He Special Summons this card via the effect of Chills's "Blizzard Egg Level 5". Later Scorch overlays this card and "Flamesaurus" (who was Level 5 through its Flip Effect) in order to Xyz Summon "Number 61: Volcasaurus". Scorch then detaches this card in order to activate the effect of "Volcasaurus" at an unspecified point. In the next episode, Chills activates the effect of "Number 19: Freezerdon" to reattach this card and "Flamesaurus" to "Volcasaurus" as Overlay Units. Later Scorch detaches this card in order to activate the effect of "Volcasaurus" again at an unspecified point.
- In the second above-mentioned episode, this card appears in a flashback Yuma has when he realizes Scorch and Chills cheating by modifying the auto shuffle function and placing the cards in their Decks in a specific order is the reason they both knew the other had a Level 5 monster at a specific point in the Duel, which initially seemed like a coincidence at first.
- In episode 25, this card appears in a flashback Yuma has when he remembers that the museum is where he and Shark both had a Tag Duel together and Astral remembers it's also where they got the fifth and sixth "Numbers" from.
