Inspired by this and Bdubs. I think the rest is self explanatory.

Addendum: for Sharknado Summoning I, II, and III, there are improved versions. That is, for example, Sharknado Summoning I, and Improved Sharknado Summoning I, etc. The only difference is that improved versions are one Spell Level greater and any distance rolls that put the caster within the area of effect are rerolled and the caster can move the Sharknado each round up to 6″ in any desired direction after the randomized movement occurs. There is no improved version of Sharknado Summoning IV.
