Plushie-complete

As stated by User:Cinnamony:

a language is only plushie-complete if it follows a set of rules created by one of my dragon plushies

Rules

1. It must be able to print the number 4.
2. It must be able to print the number 31.
3. It must be able to store 2 in a variable.

There, those are the only 3 rules.

Requirement

That is, if an Esolang is Plushie-complete, then it can support I/O or variable.

Pseudo code

i = 2
print i * 2
print 31
