弹壳骷髅宝宝

• Follows the player and attacks enemies with a green laser.
• Laser does 12.5 dps, for 3.86s, with downtime being 4.9s, essentially adding 5.5 dps

• Birthright - If the player also has [贝壳枪] , when the gun is held, the companion will alternate between its laser and a wide-angle shot similar to the Shelleton enemy.
• Shell-A-Ton - If the player has [骷髅钥匙] , Baby Good Shelleton moves and shoots much faster.
• Tea For Two - If the player also has [茶壶] , the companion will have [茶壶] 's AoE effect while reloading.
• If the player stands outside the Bullet King 's boss door, the Baby Good Shelleton may kill the Chancellor.
• The flag for unlocking Baby Good Shelleton via finishing a run appears to trigger when the High Dragun is defeated. This happens even if [拟身怪乖宝宝] is mimicking another companion. It also appears to happen even if the player has two of the same companion at the time for other reasons; for example, having two Gatling Gull companions active at the same time (via Secret Twin ) when beating the High Dragun will also unlock this item.
• The flags for unlocking Baby Good Shelleton via the blown-up chest can be attained in either order; for example, merely acquiring [拟身怪乖宝宝] after a chest has exploded at any point in your current run will unlock Baby Good Shelleton. Merely breaking a chest is not enough; it must explode when broken, yielding nothing.
• Baby Good Shelleton appears to have various other unlocking means, beyond just the two listed, though these might not have been confirmed: Merely restarting the run once the player gets [拟身怪乖宝宝] (which may trip the run-finishing flag)
• Merely starting a run with [拟身怪乖宝宝] , as The Paradox
• Beating a boss of the Hollow with any companion item equipped
• Beating a Hollow boss for the fifth time (either the same one five times, or any five Hollow bosses; it isn't clear which)
• If the Baby Good Shelleton is spawned as an enemy with Mods then it will (by default) have the Birthright synergy.

• The description of the item is an altered version of the Shelleton 's Ammonomicon entry.

Finish a run or cause a chest to explode with [拟身怪乖宝宝] .
