Near the end, Gabumon digivolves to help the kids get through the gate, as soon as he digivolves, he uses gamumons move, shout it out in garurumons voice: Blue Blaster!
Blue blaster is gabumon's, garurumon's is howling blaster.
I've seen this many times, but did you know Digimon can have more than one attack? I don't wanna be pedantic, but Gabumon's attack is Blue Blast, and maybe Garurumon has two or more attacks. I know Patamon can do Boom Bubble and Slam Attack.
Just about EVERY digimon has at least 1 move. Bye, see ya, I'm going now, nearly out the door, 'slam' I came back to tell you that I left, I'm heading out the door again... 'slam'
Has Andrew left yet?
Anyway... Andrew and Daniel are right, digimon have more than one move, (but I don't know what they are, I'm not a great fan) and Daniel is right because it probably WAS a mistake by the voice actor
