You decide whether to use Snickering Squirrel right after you see the result of the die roll.

You can use Snickering Squirrel’s ability even if Snickering Squirrel came under your control this turn. (Note that it doesn’t use the {T} symbol.)

Snickering Squirrel can be used to produce results that aren’t normally possible, such as a result of 7 on a six-sided die.

Multiple Snickering Squirrels can be used on the same die roll. In this way, you can produce results that really aren’t normally possible, such as a result of 83 on a six-sided die.
