*Note:This can only be done with the dx version of the toy.
Things you need:Prism memory(bought with the prism bicker set),dx double driver
I bet nobody has noticed 1 secret of the prism gaia memory,well if you do not know,here's the secret.Step 1:Insert your dx prism gaia memory into the double driver.Step 2:Open up your double driver, not unscrew the double driver(do not be confused), as in the henshin opening.Step 3:Close it back up real fast(immediate action after step 2),you will get a different sound than the one u get when you normally do the henshin opening.Step 4:Realise that this sound is similar to a toy you use the dx prism gaia memory on.Step 5:I do not want to be a spoiler,so just try it yourself,you will be amazed :)
Tip:Repeat steps 2-5 for around 4 times
