GIMMICKS
Brace yourself, it's going to be a long ride!
GUARDIAN ROBOT MODE
If you push the Autobot symbol on the chest, you will hear:
-"
It's time to take out the trash!"
-"
I will protect you!"
-"
I'm so excited!"
Eyes: flash
Chest lights : steady
If you push the red button located on the right upper arm, you'll hear a mechanical sound.
Eyes: flash
Chest lights: flash
BATTLE ROBOT MODE
When you transform Bumblebee from guardian to battle mode WITHOUT DEPLOYING THE CANNONS, the minute you slide down the facemask, you will hear mechanical noises and he will either say:
-"
Shield's down!"
-something I haven't been to decipher yet.
Is it "
De...feat!"?
Eyes: flash
Chest lights: steady
If you push on the Autobot symbol, whether the cannons are deployed or not, you will hear firing sounds plus:
-"
Oh... that's gonna hurt!"
-"
Neutralized!"
-some kind of Wall-E esque sound
Eyes: flash
Chest lights: steady
If you push the red button located on the right upper arm, you'll hear a mechanical sound.
Eyes: flash
Chest lights: flash
If you move the right arm up to transform it to blaster mode, you will hear the transformation sound, some gun loading sound, then a blaster pulse sound repeated a few times.
Eyes: flash at first, then steady
Chest lights: flash at first, then steady
If you push on the red button located on the upper right arm at this point, you will hear a firing sound, then...
-"
Oooooh! That's hot!"
-some radio sound
Then you'll hear the repeated blaster pulse sound.
Eyes: flash
Chest lights: steady, then flash
Blaster: steady
If you transform the blaster back to arm mode, you'll hear some mechanical sound.
Eyes: flash
Chest lights: flash
Blaster: steady
If you lift the battle mask again to revert to guardian, he will either say:
-"
Had enough?"
-"
Decepticon disabled!"
Eyes: flash
Chest lights: steady
TRANSFORMATION TO CAR MODE
When you transform Bumblebee to car mode, when you disconnect the backpack, you'll hear the transformation sound... but I think it's because you're actually "shaking" the toy when you unsnap it, seems it's actually the torso that triggers the sound.
Eyes: flash
Chest lights: flash
Blaster: flashes
When you disconnect the torso, you will also hear the transformation sound.
Eyes: flash
Chest lights: flash
Blaster: flashes
Same goes when you transform back to robot mode.
GUARDIAN CAR MODE
If you press the car into the ground toward the front, you will hear:
-ignition sound, then engine revving, then engine stopping
If you press once again while the engine sound is still going on, you will hear:
-"
Transformers! More than meets the eye!"
-"
Autobots wage their battle to destroy the evil forces of the Deceptions"
Front lights: flash
If you press on the Autobot symbol located on the hood, you will hear:
"
Nobody can catch Bumblebee!"
"
Wanna race?"
-the sound you car makes when you lock the doors with the remote
-honking sound
Front lights: steady
TRANSFORMATION TO BATTLE CAR MODE
When you swing the left cannon forward, you will hear the transformation sound (and reverse transformation if you transform him back to guardian car mode).
Cannons: flash
Front lights: flash
Then you'll hear some kind of pre-blast sound as if the weapons are loading.
If you push on the Autobot symbol located on the hood, you will hear a blasting sound then:
-another kind of Wall-E esque sound
-"
Somebody call (something I still can't figure out) sick"... it's a pretty long sentence
Cannons: flash
Front lights: steady
EDIT: Dammit! Mid-transformation, I found a new set of clips by pressing on the Autobot symbol...
-"
Reach for the sky!"
-"
Don't make me lose this thing!"
Not sure when they're supposed to trigger though. All lights flash at that time.
Pretty sure I'm omitting certain sounds and sound sequences, there are just too many of them!
