Super Mario World: 200 (any attack except for the cape) 100 (cape attack).
Since then, they've changed quite a bit. They now tend to be much larger than regular Cheep-cheeps, and have some different attacks (blue ones can spit water).
While they don't seem to have any official connection to Bowser, they are quite dangerous to adventuring heroes.
EVOLUTION:
The most complicated thing about the evolution of the Blurp is that they
are so similar to Cheep-cheeps. Some even argue that they are
Cheep-cheeps and have just been given different names.While this arguement is acceptable for the Blurps appearing in Super Mario World, the ones in Yoshi's Story are quite different. They are much larger than ordinary Cheep-cheeps, and fight differently, too.
Some have suggested that Cheep-cheeps and Blurps are actually two different species which are starting to diverge, although it's interesting to note that Blurps appeared quite a long time ago, since Yoshi's Story takes place before most of the older Mario games. Hopefully, future games will help to clear up this confusion.
These tactics are for Blurps from Yoshi's Story. For tips on fighting the Super Mario World variety, go to Cheep-cheeps.
Attack Pattern: Red ones leap out of the water and try to eat Yoshi. Blue ones pop out of the water and spit at Yoshi, trying to knock him into the drink.
Basic Strategies: You can't hurt Blurps, so just avoid them. Get as high as you can, and if forced to move lower, be quick on your feet - especially around the red ones. Advanced: I don't know of any advanced strategies for fighting these guys.
