There are some basic types of body plans that often occur. Some types of each body plan are described. The body types are listed in order of frequency when spawned from random chances. Some candidates may not actually be efficient.
These may not look like frogs, but always use their limbs in a froglike manner. Note that while all frogjumpers frogjump, the reverse is not always true. Folding Trees therefore are not frogjumpers. Mothlike is, however. The bottom wings bounce it off the ground.
Worms are, like their namesake, primarily made of repeating segments. Worms have three subgroups: normal Worms themselves are roughly cubic in segmentry; Ribbons are thin and rectangular; and Springs are long and rectangular. They can use many braintypes.
Ribbons are graceful flat sheets like this gray rolling ribbon.
Single Joint-Powered CreaturesEdit
These have one large, usually asymmetrical segment that launches the entire creature forward. An example is shown here: https://www.youtube.com/watch?v=Ri9f8d_isg0 Because the only requirement for being a single joint-powered creature is the presence of the large segment, creatures can often have other body plans at the same time, like the final creature (at 7:41) in this video.
These may or may not be able to move in high gravity, but they resist gravity breakage well and always move by twitch-cheating. They are one of the few exceptions for cheating because few other creatures can survive in high gravity and gain much fitness.
Flat-Backed Gravity SnailsEditThese resemble crabs like the 1000x Gravity Snail below.
Armored Gravity SnailsEditThese have a heavy shell and are more fragile because at higher gravities they may crush themselves with their shell.
Tree-shaped creatures resemble the dancing tree and usually have a poor sense of direction. The usual form of movement is resemblant to a flailing worm, with random jumps. Trees are formed from an L-system and so always demonstrate fractality if symmetric.
