This object was invincible except for explosions, allowing it to drop.
Every chunk generated between April 1 and April 5, 2017 had a small chance of having a locked chest in it.
Right clicking on the chest brought up a screen, and clicking on the "Go to Store" button forwarded you to the "Venture Store". It links to https://sites.google.com/view/venturestore/home Various items are sold in the Venture Store. Clicking on the proceed to checkout button triggered an ear rape in which the Universal logo was flipped, the planet turns blue and green, and a pink text reading "f**k ur ear drums" was displayed.
Entering an item into the cart caused another ear rape with the screen temporarily flashing. Brendan will remove this soon due to causing Epilepsy.
