About this effect: If this card is sent to the Graveyard: Declare either "Crashbug X", "Crashbug Y", or "Crashbug Z"; this card's name becomes the declared name while in the Graveyard.

It's possible to declare a specific card name on YGOPRO, however the name will appear as "???" as those card name aren't built in the select option. Another way to do this is to declare any card name by typing in the card, but that's the only way I can think of to achieve a similar effect.
