Mothra is a giant radioactive monster (known in Japan as kaiju) that resembles a moth. Since its film debut in the 1961 film Mothra, it has appeared in several Toho tokusatsu films, most often as a recurring character in the Godzilla franchise.
The Mothra you are seeking is in minature form. Though the area around GZ is paved and easily accessible, I do not believe a person in a wheelchair would be able to reach this cache without some assistance. Hence, the 1.5 rating. This is Muggle Central, so stealth is of utmost importance. Tweezers may be helpful and BYOP.
Congratulations Team Spank8401 on the FTF!
