Spark dolls
Otter warriors and monsters are transformed into soft glue dolls affected by the power of dark sparks. Spark dolls have a solid coat of arms on their bodies (usually on the soles of their feet). When the tip of the spark on top of the Dark Spark, Dark Virtual Spark, Galactic Spark, or Galactic Bright Spark comes into contact with the Solidified Emblem, the doll can be materialized, divided into Dark Solidification and Hyper-Solidification according to the spark.
