Even more silly shell variants with different dart arrangements to get varied spread. 

Funky Shell Lite uses Sillybutts' original rival shell instead of donutcats' to get a tighter seal and reduce the number of rival rounds behind the half length darts.
The reverse and splitter shells launch 3 darts behind 1 centered dart/round to try to get a different spread.
The remaining shells arrange half darts in various ways to require less blaster power than rival rounds while still pushing off each other to create a wider spread.
