Shiny Black Slab

The Shiny Black Slab was a pet-summoning item that spawned an Android. It was obtainable from Chests in the surface layer, but only on the Google Play version. It was obtainable on other mobile devices via trading.

This item was removed alongside all other mobile-exclusive content in the Mobile 1.3.0.7 update.

Players on Windows Phone who acquired the Shiny Black Slab via trading continue to have access to it.

Trivia

 * The Shiny Black Slab resembled a generic smartphone. Its sprite can be compared to that of the Cell Phone, except grayscale and with fewer details.
 * The Android pet was modeled after the mascot for the mobile operating system of the same name.
