Mwonvuli Ooze
Creature — Ooze
Cumulative upkeep 2 generic mana (At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay 2 generic mana for each age counter on it.)
Mwonvuli Ooze's power and toughness are each equal to 1 plus twice the number of age counters on it.
"Ewww!"

If you choose not to pay Mwonvuli Ooze’s cumulative upkeep, it will still get an age counter before being sacrificed. Its power and toughness will momentarily increase before being put into the graveyard, which might matter to certain other cards (such as Proper Burial).

Its power/toughness changes when the cumulative upkeep resolves, not when it triggers.
