Find Waldo

Waldo has infiltrated 4 (maybe more?) hunt teams to find out what everyone is up to!

Hints

I have found 4 teams with Waldo in them, what do I do with that?

Look at the team members for each of the four teams; they are quite conspicuous and will give you new places to look for Waldo.

The previous hint was not strong enough, there is too large a search space still, what should I do with that information?

Consider where would be a thematic way to search for waldo again. Where have you been looking until now? The flavortext might provide a small nudge as well.
