Yep, plus Mr. I isn't all that cheap when you upgrade him. I guess it's good that I have all those incredible coins after all -- someone said they thought that 30K would be enough to get everything... I sounds like we will need a good deal more.
Does anyone know if we can level them up once the event is over? It's going to be hard to find the time (and tokens) to get them all to 10 in the next 8 days, let alone get Syndrome in the first place.
Yes. The livecast with the game staff a few weeks ago confirmed we would still be able to level them up after the event ends. I'm guessing though they'll switch to magic at that point, rather than Incredicoins.
