Bips

Bips are an enemy type added in Revelations Chapter 2. They are sand themed enemies and show up in sandy rooms. Following the Sin Update, a lot of Bip variants have been given new attacks such as the ability to pass through sandcastles by making short dives underneath.

Sandbip
Sandbips are the lowest ranking Bip. They often wander around the room for a short time before loosely charging the player indefinitely. If a sandcastle is destroyed in the same room as one, it will avert attention to where the sandcastle was ruined and sacrifice itself to rebuild it.

Trenchbip
A Trenchbip appears as a small spike in the ground. If the player gets near, Trenchbip will emerge and chase the player. If the player goes too far away, the Trenchbip will return to his original spot and go back down into the sand. Trenchbips are always posted around sandcastles and if all sandcastles within a 3 tile square of the Trenchbip are destroyed, it will emerge and chase the player indefinitely.

Currently, the player does not need to slay all Trenchbips to clear a room.

Snipebip
Snipebips target the player with a red laser and unleash a long volley of sand tears. They sit on the corners of sandcastles, where there are invincible. If the corner they are sitting on is destroyed, they will become vulnerable; but will quickly relocate to another corner in the room. If no other corners are available, Snipebips will continue attacking on the ground level.

Bloatbip
Bloatbips track the player to spew a small arching cluster of sand projectiles when they get near.

Cannonbip
Cannonbips are stationary enemies that periodically fire Demobips at the player. When the Demobips land, a small burst of tears is sent out. Cannonbips are often placed behind destructible barriers that require the Demobips they launch to by-pass.

Demobip
Demobips loosely follow the player, exploding on contact or death similar to Mullibooms.

Slambip
Slambips wander around aimlessly for a short time before targeting a sandcastle aligned horizontally or vertically with the player. They will then emerge on the other side of the sandcastle and slam their heads forward, creating a line of rock waves towards the player. This attack can be thwarted by destroying the sandcastle before they slam.

Sandbob
Sandbobs remain hidden in the ground until the player has destroyed at least 2 sandcastles. Afterward, they will emerge and begin directly following the player. They periodically charge the player, rallying nearby bips to charge with him, which gives some of the bips different behavior. All bips except for Snipebips, Cannonbips, and Slambip's follow Sandbob over the player if there is a Sandbob in the room. Upon death, the Sandbob splits into 3 Sandbips which will often aim to repair the sandcastles that were destroyed to summon the Sandbob.
 * Sandbips: Charges in the direction they are facing for a short distance. They sometimes relocate to somewhere else in the room after charging.
 * Bloatbips: Charges in the direction they are facing for a short distance. They periodically fire a small Monstro's Lung type sand tear attack. They sometimes relocate to somewhere else in the room after charging.
 * Demobip: Charges in the direction they are facing for a short distance. They sometimes relocate to somewhere else in the room after charging.

Sandshaper
Sandshapers slowly and randomly move around the room. If they are damaged by any means, they will slam the ground, sending rock waves out in a variety of patterns: Alternatively, they may spawn a group of sand projectiles from a nearby destroyed sandcastle if any are present and then throw them towards the player.
 * Directly towards the player.
 * In a V shape towards the player.
 * In all directions around himself for a short distance.
