On one hand we might say it is a harmless message also you never can tell the motive behind such, that is, what if the plan was already in place to create such and what was needed as just that right moment. Moreover, one can hardly get involved in something that won't benefit him.
Also, on the other hand, he has already created that environment of tweeting something and the crypto community will pick it up to their own advantage, it start with Doge thus once something of like manner comes up from him, people leverages it and make money out of it, all these lead to the Meme shitcoins season.
Lastly, everything point to hype, and nothing more and today no one is remembering the Floki token again, the aim has been achieved and people have moved on; if he tweets another again, don't be surprised another token will pop up again, rise high and then crash like the others.
