Snoopy Hug and thump sleeping switch

Product Description

"Hug and Thump Sleeping Switch" is a Snoopy plush toy from Takara Tomy's Smile Tech series, officially licensed by Peanuts Worldwide LLC. It's designed to support babies' sleep routines with a combination of gentle vibration ("thump"), ambient sounds, and melodies.

The plush includes an optional heart-rate sensor unit. To use it, press the sensor pad firmly against the baby's skin (such as the arm or palm) while holding the melody switch for about 10 seconds. This one-time reading sets an initial vibration and melody tempo, which then gradually slows over time following a fixed "1/f fluctuation" rhythm pattern. The sensor does not continuously track the baby's heart rate during use, and the toy cannot display or output a numeric heart-rate value. Measurement is entirely optional — the toy works normally, starting with the womb sound and a default vibration tempo, even if this step is skipped. Once a reading has been taken, it cannot be repeated without turning the main switch off and back on. Per the manufacturer, this product is not a medical device.

Built-in audio includes a womb sound, two nature sounds (ocean waves and forest), and five melodies: Linus and Lucy, Ave Maria, Cradle Song, Twinkle Twinkle Little Star, and Brahms' Lullaby. A 3-level volume switch (off / low / high) controls sound and melody playback, though vibration continues even when the volume is set to off. After about 30 minutes without interaction, sound and vibration stop automatically.

The heart-rate sensor unit is not waterproof and should never be allowed to get wet.

Care Instructions

The plush body may be hand-washed after removing the sensor unit: use water at 30°C or below, do not use bleach, do not iron, and do not tumble dry. Reshape and air-dry flat in the shade. Wash separately, as colors may transfer. The sensor unit itself must never be washed or submerged in water — wipe it clean only with a well-wrung, damp cloth.

• The sensor unit emits a strong light during measurement; never look directly into it.
• Do not allow a child to use the sensor unit separately from the plush toy.
• This product is not a medical device and does not measure or display a numeric heart rate.
• Position the toy below shoulder level and never cover the child's face, as it vibrates repeatedly.
• Stop use and consult a doctor if the child appears unwell.
