Fast Swimming Frog has not changed much in terms of skills, with more skills that have good special effects but slightly lower power, such as Downward Spiral and Pressure Road, and the most important enhancement is the Dream Trait's Lightning Fast, although Fast Swimming Frog doesn't have a high base attack, but it has Strengthening, Durability, and Hypnosis, which are combined with the speed given by Lightning Fast, and it should be able to have a great deal of work under the rainy sky. Bullfroggy, the rainfall trait is subversive to Bullfroggy's usage, and more than that, Boiling Water is also good for a durability-biased water PM like Bullfroggy, and with the already abundant disruption skills, there's a lot more that Bullfroggy can do besides Weatherhand. So fast frogging is better.
