Astrobox

Astrobox is an unlockable skin for Boombox. It can be obtained by speaking to its NPC on top of the BoomBloxx building for 50,000 Bux. This skin depicts him as a green alien, his skin changed to suit this. He wears a black jacket with white stars on his shoulders, the cuffs of the sleeves being a white and purple pattern. The jacket has a breast pocket that holds something that resembles a radio with a purple screen, and just above it is a port in the suit for a purple tube to come out of. His pants are grey with black padding on his knees with a purple accent in the middle, alongside chunky white and purple shoes with green soles, further giving the impression of a futuristic outfit. There's a black strap across his chest with white triangles patterned along it, pointing up towards his shoulder. His mouth is a bracket resembling a smile and his eyes on his visor are now green, both triangles pointing inward. The hat he wears is the same, except now it is predominantly black with green accents. His boombox is now mostly black and cylindrical in shape with a glowing green stripe on either end, the handle of it also being green. His dialogue changes to nonsense words such as (but not limited to) "gnarp", "glorp", "glarp", and "gnorn".

When using Pulse Wave, if he lands the metronome, it creates a whirling sort of sound accompanied by a click. If he misses the metronome, the boombox just whirls. The bars coming out of the boombox appear to be a green, semi-circle, outline with some lines between it. When using Bass Boost / Beat Drop, a zipping noise followed by a high pitched whirling and when he lands, it creates a lower whirling sound accompanied by an unstable, high-pitched whirl. The leaping affect is a green circle with some lines intersecting it and landing creates a shockwave with a similar pattern. When using Protecting Overtone, an echoey whirl comes from the shield and hitting E again plays a glitchy canceling sort of sound. The shield is now green and wavy. When using Shielding Amplifier, with max bars, it'll send out a green shockwave with lines in-between the. The sound that plays is a high-pitched whirling sound. When using Raining Tacos, a green beam will "abuduct" Boombox and an 8-bit remix of Raining Tacos plays. When landing, a large, green shockwave forms and a basic whirling plays, accompanied by more 8-bit whirling sounds.

Astrobox has a green/purple tentacle dick that is also used for oviposition.
