The creeperasaurus is a therpodal creature that is roughly 2.5 blocks tall, and 5 blocks long. They have a green color scheme with black eyes and lips, much like the creeper, with a jaw like a tyrannosaur with spines on its back of it's spine and will chomp, charge, and knock the player with its tail.

(Just an extra note they have 90 hearts)

The stilagmaceratops is slightly shorter. Roughly 2.3 blocks tall and 4.5 blocks long. Their dripstone like horns are roughly the length of 1 pointed dripstone plus a trapdoor and have 3 of them with a spiky frill. They are brown like with light grey eyes and will charge, stomp, and throw boulders at the player when attacking.

(Note, the creeperasaurus will naturally attack and battle the stilagmaceratops)

The phantoraptor is a pterosaur-like creature. It is blue colored with a white back and green eyes, reminiscent of the phantom and will swoop and peck, blast wind gusts at, and pick up and drop the player. They are 4 blocks long and have a wingspan of 6 blocks.

The wardasaurus is the last mini boss. Its  5.5 blocks long and 3.2 blocks tall. They are quadrupedal nothosaur-like creatures with a color scheme similar to the warden, granted, a bit darker and will chomp, throw, and pull the player under the water.
