Volcdoramon Type: Dragon Special Moves Volcanic Font Circle of Death
Clockmon: "Volcdoramon! A huge, mountain-like Digimon who lives in an active volcano." Old Clock Shop Man: "Its Special Move is spitting out super-hot magma at the opponent (Volcanic Font)!" Ewan Amano: "DigiXros with Tuwarmon! DigiXros!" Tagiru Akashi: "Amazing! Volcdoramon's changed into Mt. Fuji!"
When Tagiru looks at his Collection, Kotemon and Fugamon are missing and Blossomon has the normal coloration of it's species rather than the correct pink petals.
When Tagiru gets excited about Hunting Volcdramon, Dobermon is drawn to be looking backward at him, although Tagiru's knee is layered over Dobermon.
When Tagiru and the others are speaking to the Old Man after defeating Volcdramon, MetalGreymon's helmet and upper horn are miscolored.
Missing and miscolored Digimon.
A perspective error.
Miscolored helmet and horn.
When Xros Heart enters the building where the Hunters are gathering, Ryouma is playing a "TOHWAY" piano. The brand name is a pun on "Toei", who produces the Digimon anime.
The title card of the episode shows the main protagonists of the previous seasons, Tai, Davis, Takato, Takuya, and Marcus. Near the end of the episode, Tai, Davis, Takato, Takuya, and Marcus both make a silhouetted cameo alongside their Digimon on the Old Clock Shop Man's boat.
This is the first episode to feature all of the non-shadowed characters from the opening.
Tai was going to have a speaking role but it got removed for time.
